The effects of digestive enzymes on characteristics of placental insulin receptor. Comparison of particulate and soluble receptor preparations. (1/3619)

The role of the surrounding membrane structure on the binding characteristics of the insulin receptor was studied by using several digestive enzymes. The effects observed with particulate membrane preparations are compared with those from soluble receptor preparations. beta-Galactosidase and neuraminidase had no effect on insulin binding to either particulate or soluble receptors from human placentae. Exposure to 2 units of phospholipase C/ml increased insulin binding to particulate membranes, but was without effect on the soluble receptor preparation. The increase in binding to particulate membranes was shown to be due to an increase in apparent receptor number. After 5 min exposure to 500 microgram of trypsin/ml there was an increase in insulin binding to the particulate membrane fraction, owing to an increase in receptor affinity. After 15 min exposure to this amount of trypsin, binding decreased, owing to a progressive decrease in receptor availability. In contrast, this concentration of trypsin had no effect on the solubilized receptor preparation. Because of the differential effects of phospholipase C and trypsin on the particulate compared with the solubilized receptor preparations, it is concluded that the effects of these enzymes were due to an effect on the surrounding membrane structure. Changes in receptor configuration due to alterations within the adjoining membrane provide a potential mechanism for mediating short-term alterations in receptor function.  (+info)

Complete sequence of a 184-kilobase catabolic plasmid from Sphingomonas aromaticivorans F199. (2/3619)

The complete 184,457-bp sequence of the aromatic catabolic plasmid, pNL1, from Sphingomonas aromaticivorans F199 has been determined. A total of 186 open reading frames (ORFs) are predicted to encode proteins, of which 79 are likely directly associated with catabolism or transport of aromatic compounds. Genes that encode enzymes associated with the degradation of biphenyl, naphthalene, m-xylene, and p-cresol are predicted to be distributed among 15 gene clusters. The unusual coclustering of genes associated with different pathways appears to have evolved in response to similarities in biochemical mechanisms required for the degradation of intermediates in different pathways. A putative efflux pump and several hypothetical membrane-associated proteins were identified and predicted to be involved in the transport of aromatic compounds and/or intermediates in catabolism across the cell wall. Several genes associated with integration and recombination, including two group II intron-associated maturases, were identified in the replication region, suggesting that pNL1 is able to undergo integration and excision events with the chromosome and/or other portions of the plasmid. Conjugative transfer of pNL1 to another Sphingomonas sp. was demonstrated, and genes associated with this function were found in two large clusters. Approximately one-third of the ORFs (59 of them) have no obvious homology to known genes.  (+info)

Modulation of acute and chronic inflammatory processes by cacospongionolide B, a novel inhibitor of human synovial phospholipase A2. (3/3619)

1. Cacospongionolide B is a novel marine metabolite isolated from the sponge Fasciospongia cavernosa. In in vitro studies, this compound inhibited phospholipase A2 (PLA2), showing selectivity for secretory PLA2 (sPLA2) versus cytosolic PLA2 (cPLA2), and its potency on the human synovial enzyme (group II) was similar to that of manoalide. 2. This activity was confirmed in vivo in the 8 h zymosan-injected rat air pouch, on the secretory enzyme accumulating in the pouch exudate. Cacospongionolide B, that is bioavailable when is given orally, reduced the elevated levels of sPLA2 present in paw homogenates of rats with adjuvant arthritis. 3. This marine metabolite showed topical anti-inflammatory activity on the mouse ear oedema induced by 12-O-tetradecanoylphorbol acetate (TPA) and decreased carrageenin paw oedema in mice after oral administration of 5, 10 or 20 mg kg(-1). 4. In the mouse air pouch injected with zymosan, cacospongionolide B administered into the pouch, induced a dose-dependent reduction in the levels of eicosanoids and tumour necrosis factor alpha (TNFalpha) in the exudates 4 h after the stimulus. It also had a weak effect on cell migration. 5. The inflammatory response of adjuvant arthritis was reduced by cacospongionolide B, which did not significantly affect eicosanoid levels in serum, paw or stomach homogenates and did not induce toxic effects. 6 Cacospongionolide B is a new inhibitor of sPLA2 in vitro and in vivo, with anti-inflammatory properties in acute and chronic inflammation. This marine metabolite was active after oral administration and able to modify TNFalpha levels, and may offer an interesting approach in the search for new anti-inflammatory agents.  (+info)

Inhibitory sites in enzymes: zinc removal and reactivation by thionein. (4/3619)

Thionein (T) has not been isolated previously from biological material. However, it is generated transiently in situ by removal of zinc from metallothionein under oxidoreductive conditions, particularly in the presence of selenium compounds. T very rapidly activates a group of enzymes in which zinc is bound at an inhibitory site. The reaction is selective, as is apparent from the fact that T does not remove zinc from the catalytic sites of zinc metalloenzymes. T instantaneously reverses the zinc inhibition with a stoichiometry commensurate with its known capacity to bind seven zinc atoms in the form of clusters in metallothionein. The zinc inhibition is much more pronounced than was previously reported, with dissociation constants in the low nanomolar range. Thus, T is an effective, endogenous chelating agent, suggesting the existence of a hitherto unknown and unrecognized biological regulatory system. T removes the metal from an inhibitory zinc-specific enzymatic site with a resultant marked increase of activity. The potential significance of this system is supported by the demonstration of its operations in enzymes involved in glycolysis and signal transduction.  (+info)

E-CELL: software environment for whole-cell simulation. (5/3619)

MOTIVATION: Genome sequencing projects and further systematic functional analyses of complete gene sets are producing an unprecedented mass of molecular information for a wide range of model organisms. This provides us with a detailed account of the cell with which we may begin to build models for simulating intracellular molecular processes to predict the dynamic behavior of living cells. Previous work in biochemical and genetic simulation has isolated well-characterized pathways for detailed analysis, but methods for building integrative models of the cell that incorporate gene regulation, metabolism and signaling have not been established. We, therefore, were motivated to develop a software environment for building such integrative models based on gene sets, and running simulations to conduct experiments in silico. RESULTS: E-CELL, a modeling and simulation environment for biochemical and genetic processes, has been developed. The E-CELL system allows a user to define functions of proteins, protein-protein interactions, protein-DNA interactions, regulation of gene expression and other features of cellular metabolism, as a set of reaction rules. E-CELL simulates cell behavior by numerically integrating the differential equations described implicitly in these reaction rules. The user can observe, through a computer display, dynamic changes in concentrations of proteins, protein complexes and other chemical compounds in the cell. Using this software, we constructed a model of a hypothetical cell with only 127 genes sufficient for transcription, translation, energy production and phospholipid synthesis. Most of the genes are taken from Mycoplasma genitalium, the organism having the smallest known chromosome, whose complete 580 kb genome sequence was determined at TIGR in 1995. We discuss future applications of the E-CELL system with special respect to genome engineering. AVAILABILITY: The E-CELL software is available upon request. SUPPLEMENTARY INFORMATION: The complete list of rules of the developed cell model with kinetic parameters can be obtained via our web site at: http://e-cell.org/.  (+info)

Do enzymes obey the Baldwin rules? A mechanistic imperative in enzymatic cyclization reactions. (6/3619)

Specific gene expression in pancreatic beta-cells: cloning and characterization of differentially expressed genes. (7/3619)

Identification and characterization of genes expressed preferentially in pancreatic beta-cells will clarify the mechanisms involved in the specialized properties of these cells, as well as providing new markers of the development of type 1 diabetes. Despite major efforts, relatively few beta-cell-specific genes have been characterized. We applied representational difference analysis to identify genes expressed selectively in the pancreatic beta-cell line betaTC1 compared with the pancreatic alpha-cell line alphaTC1 and isolated 26 clones expressed at higher levels in the beta-cells than in the alpha-cells. DNA sequencing revealed that 14 corresponded to known genes (that is, present in GenBank). Only four of those genes had been shown previously to be expressed at higher levels in beta-cells (insulin, islet amyloid polypeptide, neuronatin, and protein kinase A regulatory subunit [RIalpha]). The known genes include transcription factors (STAT6) and mediators of signal transduction (guanylate cyclase). The remaining 12 genes are absent from the GenBank database or are present as expressed sequence tag (EST) sequences (4 clones). Some of the genes are expressed in a highly specific pattern-expression in betaTC1 and islet cells and in relatively few of the non-beta-cell types examined; others are expressed in most cell types tested. The identification of these differentially expressed genes may aid in attaining a clearer understanding of the mechanisms involved in beta-cell function and of the possible immunogens involved in development of type 1 diabetes.  (+info)

Enzyme-mononucleotide interactions: three different folds share common structural elements for ATP recognition. (8/3619)

Three ATP-dependent enzymes with different folds, cAMP-dependent protein kinase, D-Ala:D-Ala ligase and the alpha-subunit of the alpha2beta2 ribonucleotide reductase, have a similar organization of their ATP-binding sites. The most meaningful similarity was found over 23 structurally equivalent residues in each protein and includes three strands each from their beta-sheets, in addition to a connecting loop. The equivalent secondary structure elements in each of these enzymes donate four amino acids forming key hydrogen bonds responsible for the common orientation of the "AMP" moieties of their ATP-ligands. One lysine residue conserved throughout the three families binds the alpha-phosphate in each protein. The common fragments of structure also position some, but not all, of the equivalent residues involved in hydrophobic contacts with the adenine ring. These examples of convergent evolution reinforce the view that different proteins can fold in different ways to produce similar structures locally, and nature can take advantage of these features when structure and function demand it, as shown here for the common mode of ATP-binding by three unrelated proteins.  (+info)

Enzymes are tremendously proficient catalysts, which can be used as extracellular catalysts for a whole host of processes, from chemical synthesis to the generation of novel biofuels. For them to be more amenable to the needs of biotechnology, however, it is often necessary to be able to manipulate their physico-chemical properties in an efficient and streamlined manner, and, ideally, to be able to train them to catalyze completely new reactions. Recent years have seen an explosion of interest in different approaches to achieve this, both in the laboratory, and in silico. There remains, however, a gap between current approaches to computational enzyme design, which have primarily focused on the early stages of the design process, and laboratory evolution, which is an extremely powerful tool for enzyme redesign, but will always be limited by the vastness of sequence space combined with the low frequency for desirable mutations. This review discusses different approaches towards computational enzyme

Using computational database searches, we have demonstrated previously that no gene sequences could be found for at least 36% of enzyme activities that have been assigned an Enzyme Commission number. Here we present a follow-up literature-based survey involving a statistically significant sample of such orphan activities. The survey was intended to determine whether sequences for these enzyme activities are truly unknown, or whether these sequences are absent from the public sequence databases but can be found in the literature. We demonstrate that for ~80% of sampled orphans, the absence of sequence data is bona fide. Our analyses further substantiate the notion that many of these enzyme activities play biologically important roles. This survey points toward significant scientific cost of having such a large fraction of characterized enzyme activities disconnected from sequence data. It also suggests that a larger effort, beginning with a comprehensive survey of all putative orphan activities, would
Introduction. THE DETERMINATION OF A RATE EQUATION Rate equation has the form rate = k [A]x[B]y which shows how the rate of a chemical reaction depends on the concentration of the reactants (A&B) and the rate constant k. The rate equation normally indicates what species are involved in the rate-determining step and how many species are involved. A rate equation is used to describe how the concentration of a product increases or the concentration of the reactants decreases with time, the equation also indicates how the concentration of one or more reactants directly affects the rate. Occasionally it can even be the concentration of a product that affects the rate. In general the rate equation for the reaction: A + B C + D Is found by experiment to follow simple kinetics with the rate equation being written as: Rate = k [A]x[B]y k = rate constant, x = order with respect to [A], y = order with respect with [B]. There are three orders of reactions, zero order, first order and second order. Zero ...

Since 2003 the STRENDA Commission (Standards for Reporting Enzyme Data) is concerned with the improvement of the quality of reporting functional enzyme data to support the community with the efficient application of enzyme kinetics in the in vivo, in vitro and in silico investigation of biological systems. The Commission has two major goals: One is the development of a set of guidelines for the reporting of data in publications. These guidelines have already been adopted by a number of biochemistry journals. The second goal is the development of an electronic data submission tool which incorporates the STRENDA Guidelines, and which is intended to act as a portal for the submission of enzyme kinetics data to a freely accessible, public database.. This 5th ESCEC symposium, organized by the Beilstein-Institut together with the STRENDA Commission, provides a platform to discuss standards in biochemistry in general and the STRENDA Guidelines in particular. The meeting also brings together ...

The interface between biology and chemistry is fertile ground for the development of new computational techniques. Yet it is still hard to predict protein-ligand binding, model protein folding or design effective pharmaceutical products.. Enzyme-catalysed reactions are ubiquitous and essential to the chemistry of life. Structures, gene sequences, mechanisms, metabolic pathways and kinetic data are currently spread between many different databases and throughout the literature. We have created MACiE, the worlds first comprehensive electronic database of the chemical mechanisms of enzymatic reactions. We are using MACIE to investigate fundamental questions about the chemistry of enzyme functions, their evolution, and their substrate specificity. Improving the prediction of solubility is essential to reduce the current unacceptable attrition rate in drug development. We are developing methods to predict aqueous solubility for drug-like molecules, and hope to move on to study its dependence on pH, ...

In order to understand the evolution of enzyme reactions and to gain an overview of biological catalysis we have combined sequence and structural data to generate phylogenetic trees in an analysis of 276 structurally defined enzyme superfamilies, and used these to study how enzyme functions have evolved. We describe in detail the analysis of two superfamilies to illustrate different paradigms of enzyme evolution. Gathering together data from all the superfamilies supports and develops the observation that they have all evolved to act on a diverse set of substrates, whilst the evolution of new chemistry is much less common. Despite that, by bringing together so much data, we can provide a comprehensive overview of the most common and rare types of changes in function. Our analysis demonstrates on a larger scale than previously studied, that modifications in overall chemistry still occur, with all possible changes at the primary level of the Enzyme Commission (E.C.) classification observed to a ...

but about 0.6 mol. Thus it is recommended that hybrid equations, in which some charges but not others are given, should be avoided as misleading.. If these recommendations were to be implemented, the following paragraph would have to be added to Note (1) on page 23 of Enzyme nomenclature 1992 [14]:. Since the equations representing the reactions are biochemical equations, they provide the basis for writing the expression for the apparent equilibrium constant K at specified T, P, pH, pX and ionic strength. Here pX = -log[X] where X is any metal ion that is bound by the reactants. Biochemical equations do not balance hydrogen atoms, atoms of the bound metal or charge, but they do balance other kinds of atoms. The expression for the apparent equilibrium constant K for any reaction can be written by looking at the biochemical equation. Chemical equations that do balance hydrogen ions, bound metal ions and charge can be written for these reactions and their equilibrium-constant expressions yield ...

Plants make many valuable compounds, but often in small quantities, says John Shanklin, the lead biologist on the study. Though not the direct focus of Shanklins work, examples could include medicinal compounds and oils that may be useful as raw materials for industrial processes. Shanklin suggests that the reason for such poor production in nature is that the enzymes responsible are newly evolved. That may seem strange, because many people associate evolution with improvement. But when enzymes evolve new functions, they almost always lose efficiency, he says. Enzymes are proteins that speed up chemical reactions by bringing the reacting molecules together like pieces of a puzzle. Like all proteins, theyre made of chains of building blocks called amino acids, folded in a precise way to give the enzyme its three-dimensional shape. In nature, new enzymes arise from random mutations in the genes that code for the amino-acid sequence. Most changes have no effect. A very small percentage improve ...
It is not possible to explain everything about enzymes, but I will try to explain why the answer is D. First of all, enzymes are catalysts, meaning they increase the reaction rates of chemical reactions. A and B speak about the concentration of substrate. What is important to know is that the rate of reaction of the enzyme-catalyzed reaction depends on the amount of substrate (reactants) you are given. This means that as you are given more substrate, enzymes become active in order to breakdown more of the substrate. On the other hand, if you are given less substrate, the enzymes arent required to catalyze as many reactions than if there were large amount of substrates. I cannot explain C just because you need to know that all enzymes are proteins, but not necessarily the other way around (just like how a square is a rectangle, but a rectangle is not a square). Therefore, the answer is D ...

I cannot explain C just because you need to know that all enzymes are proteins, but not necessarily the other way around (just like how a square is a rectangle, but a rectangle is not a square). Therefore, the answer is D ...
Hello, This question might seem easy, but I found it not so obvious as I thought about it more: What does rate limiting mean to you ? It is used quite often, and not only in biology. The example I am dealing with is a common one, a metabolic pathway. The simplest way to see it, is that there is not RenoughS of the first enzyme on the pathway and RplentyS of the following enzymes. When more of the first enzyme is made, the flux through the pathway increases in a direct (not necessarily linear) function of this first enzyme. Does it mean that this first enzyme is used at saturation of its substrate(s) ? If not, the element that keeps those substrate(s) constant would be the real rate limiting step by providing the right flux of substrate so as to keep it constant ! If that flux does not change, an increase in the quantity and consequently in flux of the first enzyme would have the effect of lowering the concentration of its substrate until the activity was restored to its original value ! I feel ...

Brenda Trenowden of all people understands the lack of female representation in executive positions. Head of Financial Institutions Group for Europe, and Head of Banks and Diversified Financials E&A for ANZ, she is now the new Global Head of the 30% Club, a campaign that aims to reach the minimum of 30% women on FTSE-100 boards.. Facts on this issue are painful to look at. Women make up 27% of FTSE-100 boards, 23.2% of FTSE-350 boards, and just 19.4% of FTSE 100 ExCos. But the reasons behind this are far from simple. Trenowden explained how it begins when women first go into work. There is definitely a difference between how men and women present themselves, and how managers interpret how women and men present themselves … men tend to present themselves in an overconfident way quite often, while women tend to be a bit realistic and risk-averse. Because men predominately set-up or run organisations, when they fail to take into account these differences women are promoted less.. But the ...

Enzyme nomenclature was formalized in the 1950s. It is formulated by the International Union of Biochemistry (IUB) and the International Union of Pure and Applied Chemistry (IUPAC), more specifically, the Nomenclature Committee of the International Union of Biochemistry and Molecular Biology (NC-IUBMB) and the IUPAC-IUB Joint Commission on Biochemical Nomenclature. There are around 3500 listed enzymes. Officially assigned names and numbers for enzymes are available at the Enzyme Nomenclature Database: http://www.chem.qmul.ac.uk/iubmb/enzyme/. Rules for enzyme nomenclature are available at http://www.chem.qmul.ac.uk/iubmb/enzyme/rules.html. There are 3 types of enzyme name: recommended name (common, working, or trivial name), systematic name, and Enzyme Commission (EC) number.

As the ultimate stage of stellar nucleosynthesis, and the source of the iron peak nuclei, silicon burning is important to our understanding of the evolution of massive stars and supernovae. Our reexamination of silicon burning, using results gleaned from simulation work done with a large nuclear network (299 nuclei and more than 3000 reactions) and from independent calculations of equilibrium abundance distributions, offers new insights into the quasi-equilibrium mechanism and the approach to nuclear statistical equilibrium. We find that the degree to which the matter has been neutronized is of great importance, not only to the final products but also to the rate of energy generation and the membership of the quasi-equilibrium groups. A small increase in the global neutronization results in much larger free-neutron fluences, increasing the abundances of more neutron-rich nuclei. As a result, incomplete silicon burning results in neutron richness among the isotopes of the iron peak much larger than the
All three types of reaction participants are linked to the ChEBI database (Chemical Entities of Biological Interest) which provides detailed information about structure, formula and charge. Rhea provides built-in validations that ensure both mass and charge balance of the reactions. We have populated the database with the reactions found in the enzyme classification (i.e. in the IntEnz and ENZYME databases), extending it with additional known reactions of biological interest. While the main focus of Rhea is enzyme-catalysed reactions, other biochemical reactions (including those that are often termed spontaneous) also are included ...
Although domain-centric annotations hold great promise in describing phenotypic nature of independent domains, most domains themselves may not just work alone. In multi-domain proteins, they may be combined together to form distinct domain architectures. The recombination of the existing domains is considered as one of major driving forces for phenotypic diversificaation. As an extension, we have also generated supra-domain phenotype ontology and its annotations. Compared to domain-centric phenotype ontology and annotations (SCOP domains at the Superfamily level and Family level), this version focuses on supra-domains and individual SCOP domains ONLY at the Superfamily level. Besides, in terms of individual superfamilies, their annotations from the domain-centric version may be different from those from supra-domains version. Depending on your focus, the former should be used for the consideration of both the Superfamily level and Family level, otherwise the latter should be used if you are ...
Introduction [ 3 ]. Enzyme dynamicss is the survey of survey of the rates of chemical reactions that are catalyzed by enzymes. The rates of an enzyme catalyzed reaction by and large changes with alteration in enzyme concentration, substrate concentration, temperature, pH, clip, and presence of enzyme inhibitors. Enzymes are protein accelerators that, like all accelerators, speed up the rate of a chemical reaction without being used up in the procedure.. Catalyst [ 1 ] : A accelerator is a substance, other than a reactant or a merchandise, that enhances the rate of reaction and remains unchanged at the terminal of the reaction. The accelerator does non alter the equilibrium invariable of reaction, it merely accelerates the rate of reaction in forward and rearward way.. Assay of Enzyme Activity [ 1 ]. For most of the enzymes, the rate of the enzyme-catalysed reaction is a map of the entire enzyme concentration ( [ E ] ) , concentration of substrate ( [ S ] ) , and inhibitors, pH, temperature, and ...
The amino acid sequences of 301 glycosyl hydrolases and related enzymes have been compared. A total of 291 sequences corresponding to 39 EC entries could be classified into 35 families. Only ten sequences (less than 5% of the sample) could not be assigned to any family. With the sequences available for this analysis, 18 families were found to be monospecific (containing only one EC number) and 17 were found to be polyspecific (containing at least two EC numbers). Implications on the folding characteristics and mechanism of action of these enzymes and on the evolution of carbohydrate metabolism are discussed. With the steady increase in sequence and structural data, it is suggested that the enzyme classification system should perhaps be revised. ...
This all-natural supplement assists in the digestion and absorption of nutrients critical to good health.. The plant enzymes and probiotics work to break down fats, carbohydrates, cellulose and protein so the body can utilize them. Digestive enzymes are not stored in the body, instead they are produced at the time of each feeding triggered by anticipation of eating or the aromas of the food. But as the body ages it produces fewer enzymes, so supplementation is necessary for optimum health. A digestive aid is also necessary when the animal is affected by excitement, anxiety or stress such as travel or separation, which disrupt digestion. In addition, this formula replenishes natural enzymes in pet food that are typically destroyed by heat proceesing or oxidation. Animal Essentials enzymes contain a blend of plant and microbial enzymes, none of which come from animal sources. Animal-derived enzymes work in only one area of the digestive system, while plant and microbial enzymes work throughout ...
We analyzed water and sediment chemistry, catchment land cover, and extracellular enzymes (ecoenzymes) activities related to microbial C, N, and P acquisition in more than 2100 1st- 10th order streams. Streams were selected from a probability design to represent the entire population of streams in the conterminous United States. Streams and their catchments were aggregated into nine ecoregions representing coastal and interior plains, eastern and western mountains, the Laurentian Great Lakes basin, or xeric western lowlands. There were significant ecoregions differences for all of the water chemistry variables: ANC, DOC, TN and TP were all lowest in the mountain streams; SO4, TN and TP were highest in plains streams. Sediment chemistry also varied across ecoregions. Biofilm and sediment ecoenzyme activity exhibited ecoregional trends correlated with stream and sediment chemistry and with catchment land cover. Oxidases (enzymes that degrade recalcitrant C) represented 80-90% of the biofilm ...
This article by Dr. Saad Musbah Alasil and Dr. Khairul Anuar Abdullah is published in The Open Microbiology Journal, Volume 13, 2019. Malaysia is facing many challenges caused by various parasitic pathogens. The lack of awareness among disadvantaged populations such as the Orang Asli community and the dependency on foreign workers has led to an influx of immigrants to Malaysia from countries endemic with various parasitic diseases. Amoebiasis is mainly encountered in poor rural areas in Malaysia, however it has the potential to re-emerge. Routine mass-drug administration on newly arriving foreign workers and health education programs are needed to prevent its re-emergence.. Researchers from MAHSA University in Malaysia have published a review on the epidemiology of various parasitic diseases in the country over the last 20 years. The report has been published in The Open Microbiology Journal. The report stresses that Malaysian authorities must implement strategies that provide better water ...

This was something that I did not want to blog about at face value. I typed the drug name into Google Scholar to see what primary literature I could find on the subject. Here is some real information I have found:
It has been requested that, except for other cases where a concrete direction is assigned, this must be changed to use the bidirectional reaction (BI).. Once the Rhea reactions have been normalised - very very soon -, i.e. they share all of their attributes except for Rhea ID, direction and cross-references, this change of assignment will be done programatically.. It must be emphasised, even so evident it may seem, that UN means LR or RL or BI while BI means LR and RL. Thus, enzymes will have assigned a reaction which occurs in both directions at the same time. ...
This thesis is divided into four parts, all centered around Constitutional Dynamic Chemistry (CDC) and Dynamic Kinetic Resolution (DKR) using biocatalysts for selective transformations, and their applications in screening of bioactive compounds, organic synthesis, and enzyme classification. In part one, an introduction to CDC and DKR is presented, illustrating the basic concepts, practical considerations and potential applications of such dynamic systems, thus providing the background information for the studies in the following chapters. In part two, Dynamic Systemic Resolution (DSR), a concept based on CDC is exemplified. With enzyme-catalyzed transformations as external selection pressure, optimal structures can be selected and amplified from the system. This concept is expanded to various types of dynamic systems containing single, double cascade/parallel, and multiple reversible reactions. In addition, the substrate selectivity and catalytic promiscuity of target enzymes are also ...

There is evidence that selectivity against target microorganisms may be owed to various defense and susceptibility capabilities of the host and target organism, respectively. Microorganisms may have the capacity to degrade plant toxins (Osbourn, 1996) or synthesize inhibitors of toxic enzyme activities (Simmons, 1994; Ham et al., 1997) just as plants synthesize inhibitors of microbial enzymes for defense (Supplemental Table II; www.plantphysiol.org).. The target specificity of plant antimicrobial proteins/peptides appears to be determined by pathogen-specific cell surface and intracellular determinants (Table II; www.plantphysiol.org). Microbial cell surfaces harbor components that increase or decrease the efficacy of antimicrobials. Osmotin, a tobacco (Nicotiana tabacum) PR-5 protein, binds to phosphomannan, the cell wall polyanion of yeast (Saccharomyces cerevisiae). Polyanion binding is required for maximal toxicity to walled cells but not spheroplasts, suggesting that it promotes osmotin ...
Food and feed contamination by aflatoxin (AF)B1 has adverse economic and health consequences. AFB1 degradation by microorganisms or microbial enzymes provides a promising preventive measure. To this end, the present study tested 43 bacterial isolates collected from maize, rice, and soil samples for AFB1-reducing activity. The higher activity was detected in isolate L7, which was identified as Bacillus shackletonii. L7 reduced AFB1, AFB2, and AFM1 levels by 92.1%, 84.1%, and 90.4%, respectively, after 72 h at 37 °C. The L7 culture supernatant degraded more AFB1 than viable cells and cell extracts; and the degradation activity was reduced from 77.9% to 15.3% in the presence of proteinase K and sodium dodecyl sulphate. A thermostable enzyme purified from the boiled supernatant was designated as Bacillus aflatoxin-degrading enzyme (BADE). An overall 9.55-fold purification of BADE with a recovery of 39.92% and an activity of 3.85 × 103 U·mg−1 was obtained using chromatography on DEAE-Sepharose. BADE had

Molecular motors play important roles within a biological cell, performing functions such as intracellular transport and gene transcription. Recent experimental work suggests that there are many plausible biochemical mechanisms that molecules such as myosin-V could use to achieve motion. To account for the abundance of possible discrete-stochastic frameworks that can arise when modeling molecular motor walks, a generalized and straightforward graphical method for calculating their dynamic properties is presented. It allows the calculation of the velocity, dispersion, and randomness ratio for any proposed system through analysis of its structure. This article extends work of King and Altman [A schematic method of deriving the rate laws of enzyme-catalyzed reactions, J. Phys. Chem. 60, 1375-1378 (1956)] on networks of enzymatic reactions by calculating additional dynamic properties for spatially hopping systems. Results for n-state systems are presented: single chain, parallel pathway, divided ...

A complete and balanced set of enzyme activities is required for maintaining homeostasis. Enzyme kinetics, the quantitative measurement of the rates of enzyme-catalyzed reactions and the systematic study of factors that affect these rates, constitutes a central tool for the analysis, diagnosis, and treatment of the enzymic imbalances that underlie numerous human diseases. For example, kinetic analysis can reveal the number and order of the individual steps by which enzymes transform substrates into products, and in conjunction with site-directed mutagenesis, kinetic analyses can reveal details of the catalytic mechanism of a given enzyme. In the blood, the appearance or a surge in the levels of particular enzymes serve as clinical indicators for pathologies such as myocardial infarctions, prostate cancer, and damage to the liver. The involvement of enzymes in virtually all physiologic processes makes them the targets of choice for drugs that cure or ameliorate human disease. Applied enzyme ...
