Lysine deficiency alters diet selection without depressing food intake in rats. (1/9069)

Under states of protein deficiency, the dietary limiting amino acid, rather than protein content, can act as the dietary stimulus to control diet selection. If fact, threonine-deficient rats will alter their diet selection patterns solely on the basis of very small changes (0.009 g/100 g) in the dietary threonine concentration. In these studies, we assessed whether lysine-deficient rats will also alter their diet selection patterns on the basis of small changes in dietary Lys concentration. In all experiments, growing rats were adapted to diets in which the protein fraction (purified amino acids or wheat gluten) was limiting in Lys. They were then given a choice between the adaptation diet (AD) diet and a slightly more deficient diet. Rats that were adapted to a Lys-deficient diet (0.25 g Lys/100 g) selected their AD over diets containing as little as 0.01% less Lys (P < 0.01) within 5 d. To determine how deficient rats must be before they alter their selection patterns, rats were adapted to diets containing various levels of Lys, i.e., 2 levels below the requirement for growth and 2 levels above the requirement for growth, but below the requirement for maximal nitrogen retention. Only rats adapted to diets containing Lys below their requirement for growth selected their AD over a diet containing 0.05% less Lys (P < 0.005). Finally, to determine whether rats will alter their selection to whole protein-based diets, rats were adapted to 25% wheat gluten diets supplemented with 0.03-0.21% Lys. Rats selected the AD over a diet containing as little as 0.09% less supplemental Lys by d 4 of the trial (P < 0.05). We conclude that rats are sensitive to changes as small as 0.01% in dietary Lys concentration, but that sensitivity requires prior adaptation to Lys-deficient diets.  (+info)

Expanded lysine acetylation specificity of Gcn5 in native complexes. (2/9069)

The coactivator/adaptor protein Gcn5 is a conserved histone acetyltransferase, which functions as the catalytic subunit in multiple yeast transcriptional regulatory complexes. The ability of Gcn5 to acetylate nucleosomal histones is significantly reduced relative to its activity on free histones, where it predominantly modifies histone H3 at lysine 14. However, the association of Gcn5 in multisubunit complexes potentiates its nucleosomal histone acetyltransferase activity. Here, we show that the association of Gcn5 with other proteins in two native yeast complexes, Ada and SAGA (Spt-Ada-Gcn5-acetyltransferase), directly confers upon Gcn5 the ability to acetylate an expanded set of lysines on H3. Furthermore Ada and SAGA have overlapping, yet distinct, patterns of acetylation, suggesting that the association of specific subunits determines site specificity.  (+info)

Control of ketogenesis from amino acids. IV. Tissue specificity in oxidation of leucine, tyrosine, and lysine. (3/9069)

In vitro and in vivo studies were made on the tissue specificity of oxidation of the ketogenic amino acids, leucine, tyrosine, and lysine. In in vitro studies the abilities of slices of various tissues of rats to form 14CO2 from 14C-amino acids were examined. With liver, but not kidney slices, addition of alpha-ketoglutarate was required for the maximum activities with these amino acids. Among the various tissues tested, kidney had the highest activity for lysine oxidation, followed by liver; other tissues showed very low activity. Kidney also had the highest activity for leucine oxidation, followed by diaphragm; liver and adipose tissue had lower activities. Liver had the highest activity for tyrosine oxidation, but kidney also showed considerable activity; other tissues had negligible activity. In in vivo studies the blood flow through the liver or kidney was stopped by ligation of the blood vessels. Then labeled amino acids were injected and recovery of radioactivity in respiratory 14CO2 was measured. In contrast to results with slices, no difference was found in the respiratory 14CO2 when the renal blood vessels were or were not ligated. On the contrary ligation of the hepatic vessels suppressed the oxidations of lysine and tyrosine completely and that of leucine partially. Thus in vivo, lysine and tyrosine seem to be metabolized mainly in the liver, whereas leucine is metabolized mostly in extrahepatic tissues and partly in liver. Use of tissue slices seems to be of only limited value in elucidating the metabolisms of these amino acids.  (+info)

Actions of a pair of identified cerebral-buccal interneurons (CBI-8/9) in Aplysia that contain the peptide myomodulin. (4/9069)

A combination of biocytin back-fills of the cerebral-buccal connectives and immunocytochemistry of the cerebral ganglion demonstrated that of the 13 bilateral pairs of cerebral-buccal interneurons in the cerebral ganglion, a subpopulation of 3 are immunopositive for the peptide myomodulin. The present paper describes the properties of two of these cells, which we have termed CBI-8 and CBI-9. CBI-8 and CBI-9 were found to be dye coupled and electrically coupled. The cells have virtually identical properties, and consequently we consider them to be "twin" pairs and refer to them as CBI-8/9. CBI-8/9 were identified by electrophysiological criteria and then labeled with dye. Labeled cells were found to be immunopositive for myomodulin, and, using high pressure liquid chromatography, the cells were shown to contain authentic myomodulin. CBI-8/9 were found to receive synaptic input after mechanical stimulation of the tentacles. They also received excitatory input from C-PR, a neuron involved in neck lengthening, and received a slow inhibitory input from CC5, a cell involved in neck shortening, suggesting that CBI-8/9 may be active during forward movements of the head or buccal mass. Firing of CBI-8 or CBI-9 resulted in the activation of a relatively small number of buccal neurons as evidenced by extracellular recordings from buccal nerves. Firing also produced local movements of the buccal mass, in particular a strong contraction of the I7 muscle, which mediates radula opening. CBI-8/9 were found to produce a slow depolarization and rhythmic activity of B48, the motor neuron for the I7 muscle. The data provide continuing evidence that the small population of cerebral buccal interneurons is composed of neurons that are highly diverse in their functional roles. CBI-8/9 may function as a type of premotor neuron, or perhaps as a peptidergic modulatory neuron, the functions of which are dependent on the coactivity of other neurons.  (+info)

pKa calculations for class A beta-lactamases: influence of substrate binding. (5/9069)

Beta-Lactamases are responsible for bacterial resistance to beta-lactams and are thus of major clinical importance. However, the identity of the general base involved in their mechanism of action is still unclear. Two candidate residues, Glu166 and Lys73, have been proposed to fulfill this role. Previous studies support the proposal that Glu166 acts during the deacylation, but there is no consensus on the possible role of this residue in the acylation step. Recent experimental data and theoretical considerations indicate that Lys73 is protonated in the free beta-lactamases, showing that this residue is unlikely to act as a proton abstractor. On the other hand, it has been proposed that the pKa of Lys73 would be dramatically reduced upon substrate binding and would thus be able to act as a base. To check this hypothesis, we performed continuum electrostatic calculations for five wild-type and three beta-lactamase mutants to estimate the pKa of Lys73 in the presence of substrates, both in the Henri-Michaelis complex and in the tetrahedral intermediate. In all cases, the pKa of Lys73 was computed to be above 10, showing that it is unlikely to act as a proton abstractor, even when a beta-lactam substrate is bound in the enzyme active site. The pKa of Lys234 is also raised in the tetrahedral intermediate, thus confirming a probable role of this residue in the stabilization of the tetrahedral intermediate. The influence of the beta-lactam carboxylate on the pKa values of the active-site lysines is also discussed.  (+info)

Characterisation of the conformational and quaternary structure-dependent heparin-binding region of bovine seminal plasma protein PDC-109. (6/9069)

PDC-109, the major heparin-binding protein of bull seminal plasma, binds to sperm choline lipids at ejaculation and modulates capacitation mediated by heparin. Affinity chromatography on heparin-Sepharose showed that polydisperse, but not monomeric, PDC-109 displayed heparin-binding capability. We sought to characterise the surface topology of the quaternary structure-dependent heparin-binding region of PDC-109 by comparing the arginine- and lysine-selective chemical modification patterns of the free and the heparin-bound protein. A combination of reversed-phase peptide mapping of endoproteinase Lys-C-digested PDC-109 derivatives and mass spectrometry was employed to identify modified and heparin-protected residues. PDC-109 contains two tandemly arranged fibronectin type II domains (a, Cys24-Cys61; b, Cys69-Cys109). The results show that six basic residues (Lys34, Arg57, Lys59, Arg64, Lys68, and Arg104) were shielded from reaction with acetic anhydride and 1,2-cyclohexanedione in heparin-bound PDC-109 oligomers. In the 1H-NMR solution structures of single fibronectin type II domains, residues topologically equivalent to PDC-109 Arg57 (Arg104) and Lys59 lay around beta-strand D on the same face of the domain. In full-length PDC-109, Arg64 and Lys68 are both located in the intervening polypeptide between domains a and b. Our data suggest possible quaternary structure arrangements of PDC-109 molecules to form a heparin-binding oligomer.  (+info)

Role of a conserved lysine residue in the peripheral cannabinoid receptor (CB2): evidence for subtype specificity. (7/9069)

The human cannabinoid receptors, central cannabinoid receptor (CB1) and peripheral cannabinoid receptor (CB2), share only 44% amino acid identity overall, yet most ligands do not discriminate between receptor subtypes. Site-directed mutagenesis was employed as a means of mapping the ligand recognition site for the human CB2 cannabinoid receptor. A lysine residue in the third transmembrane domain of the CB2 receptor (K109), which is conserved between the CB1 and CB2 receptors, was mutated to alanine or arginine to determine the role of this charged amino acid in receptor function. The analogous mutation in the CB1 receptor (K192A) was found to be crucial for recognition of several cannabinoid compounds excluding (R)-(+)-[2, 3-dihydro-5-methyl-3-[(4-morpholinyl)methyl]pyrrolo[1,2,3-de]-1, 4-benzoxazin-6-yl](1-naphthalenyl)methanone (WIN 55,212-2). In contrast, in human embryonic kidney (HEK)-293 cells expressing the mutant or wild-type CB2 receptors, we found no significant differences in either the binding profile of several cannabinoid ligands nor in inhibition of cAMP accumulation. We identified a high-affinity site for (-)-3-[2-hydroxyl-4-(1, 1-dimethylheptyl)phenyl]-4-[3-hydroxyl propyl] cyclohexan-1-ol (CP-55,940) in the region of helices 3, 6, and 7, with S3.31(112), T3.35(116), and N7.49(295) in the K109A mutant using molecular modeling. The serine residue, unique to the CB2 receptor, was then mutated to glycine in the K109A mutant. This double mutant, K109AS112G, retains the ability to bind aminoalkylindoles but loses affinity for classical cannabinoids, as predicted by the molecular model. Distinct cellular localization of the mutant receptors observed with immunofluorescence also suggests differences in receptor function. In summary, we identified amino acid residues in the CB2 receptor that could lead to subtype specificity.  (+info)

Passive electrotonic properties of rat hippocampal CA3 interneurones. (8/9069)

1. The linear membrane responses of CA3 interneurones were determined with the use of whole-cell patch recording methods. The mean input resistance (RN) for all cells in this study was 526 +/- 16 MOmega and the slowest membrane time constant (tau0) was 73 +/- 3 ms. 2. The three-dimensional morphology of 63 biocytin-labelled neurones was used to construct compartmental models. Specific membrane resistivity (Rm) and specific membrane capacitance (Cm) were estimated by fitting the linear membrane response. Acceptable fits were obtained for 24 CA3 interneurones. The mean Rm was 61.9 +/- 34.2 Omega cm2 and the mean Cm was 0.9 +/- 0.3 microF cm-2. Intracellular resistance (Ri) could not be resolved in this study. 3. Examination of voltage attenuation revealed a significantly low synaptic efficiency from most dendritic synaptic input locations to the soma. 4. Simulations of excitatory postsynaptic potentials (EPSPs) were analysed at both the site of synaptic input and at the soma. There was little variability in the depolarization at the soma from synaptic inputs placed at different locations along the dendritic tree. The EPSP amplitude at the site of synaptic input was progressively larger with distance from the soma, consistent with a progressive increase in input impedance. 5. The 'iso-efficiency' of spatially different synaptic inputs arose from two opposing factors: an increase in EPSP amplitude at the synapse with distance from the soma was opposed by a nearly equivalent increase in voltage attenuation. These simulations suggest that, in these particular neurones, the amplitude of EPSPs measured at the soma will not be significantly affected by the location of synaptic inputs.  (+info)

Three hundred arid fifty three lactating sows were used to determine the effects of increased dietary lysine on sow and litter performance. At farrowing, sows were assigned to com-soybean meal lactation diets consisting of either 1.0 or 1.3% total lysine. A treatment by parity interaction was observed, with first parity sows fed 1.3% lysine having heavier litter weaning weights than sows fed 1.00/0 lysine. Surprisingly, third and fourth parity sows fed 1.3% lysine had lower litter weaning weights than those fed 1.0% lysine. No other treatment by parity interactions existed. No differences were observed in the number of pigs weaned or pig survivability. Sows fed 1.3 % lysine tended to consume less feed in the first week of lactation than sow fed 1.0% lysine (9.6 vs 10.0 Ibid), with no differences observed during week 2 or overall. No differences were observed in subsequent performance of the sows on days to estrus; farrowing rate; or number of pigs born, born alive, stillborn, or born mummified. ...

AU - Kass, Philip H. AU - Lappin, Michael R.. AU - Rogers, Quinton. AU - Waldron, Mark K.. AU - Fascetti, Andrea J. PY - 2007/4. Y1 - 2007/4. N2 - To determine the effectiveness of dietary lysine supplementation in cats with enzootic upper respiratory disease (URD), 50 cats were fed a ration containing 11 or 51 g lysine/kg diet for 52 days. Food intake, body weight, clinical signs, plasma amino acid concentrations and presence of Chlamydophila felis or feline herpesvirus (FHV)-1 DNA within the conjunctival fornix were assessed. Food and lysine intake of both dietary groups decreased between days 17 and 22, coinciding with peak disease and viral presence. Mean disease score for cats fed the supplemented ration (0.94) was higher than for those fed the basal diet (0.21); however, this could be attributed to a ...
A 14-day growth trial was conducted to determine the threonine: lysine ratio necessary to optimize growth performance of the segregated early-weaned (SEW) pig. Twelve experimental diets included two levels of lysine (1.15% and 1.5% apparent digestible lysine) and six apparent digestible threonine: lysine ratios (40, 45, 50, 55, 60, and 65 %) in a 2 x 6 factorial arrangement. Growth performance was improved by feeding 1.5% rather than 1.15% digestible lysine. Growth performance decreased linearly as the digestible threonine: lysine ratio increased. Although a significant quadratic response was not observed, this reduction in growth performance did not appear to occur until the threonine ratio exceeded 45% of lysine on an apparent digestible basis. These data indicate that the threonine requirement for the SEW pig is approximately 45% of digestible lysine ...
Enoyl-coenzyme A hydratase/3-hydroxyacyl-coenzyme A (EHHADH) is an important enzyme which catalyze two steps in fatty acid oxidation. There are four acetylated lysine residues been identified in EHHADH, which are Lys165, Lys171, Lys346 and Lys584. Immunoprecipitation of ectopically expressed FLAG-tagged EHHADH and Western blotting with antibody to acetyllysine confirmed that EHHADH was indeed acetylated(Zhao, et al). In order to explore the effect of acetylation on fatty acid oxidation. Isobaric tags are used, which is TSA and NAM. TSA and NAM treatment increased all the four lysine residues acetylation. Consistently, corresponding unacetylated peptide was decreased. Scientists treat TSA and NAM to Chang Human Liver cells doubled the activity of EHHADH, which indicates that acetylation of EHHADH would increase fatty acid oxidation pathway. In order to confirm the result, site-directed mutagenesis was used and the four lysine residue was replaced by glutamine, TSA and NAM can no longer ...
Histidine - Arthritis Fighter. Lysine - Herpes Killer. L-lysine is an essential amino acid. Experimental animals on a lysine-deficient diet showed depressed growth and altered immune system function for several generations.. Normal requirements for lysine have been found to be about 8 g per day or 12 mg/kg in adults.

Lysine is an amino acid, found widely in animal foods like meat, fish, and eggs, but now wildly popular as a supplement. Lysine has multiple benefits for both acne and health. Firstly, lysine is vital for collagen production, and therefore anti-ageing and strong skin. Both lysine and a structurally related compound it forms called allysine are raw materials for all collagen in your skin.. Secondly, lysine is an excellent remedy for stress, being known to reduce stress hormones strongly. Lysine activates the same receptors as benzos, the classic pharmaceutical anti-anxiety drugs, and it does so naturally. Lysine can even control serotonin receptors linked to anxiety.. Who is most at risk of deficiency? Easily vegans, vegetarians, and people who restrict animal foods for health. Unless youre smart and tactically eat the correct nuts and seeds using a meticulous system, lysine can be hard to obtain from plants alone.. That said, anyone can be lysine deficient. Is your skin weak, your face dull and ...
Lysine propionylation and butyrylation are protein modifications that were recently identified in histones. The molecular components involved in the two protein modification pathways are unknown, hindering further functional studies. Here we report identification of the first three in vivo non-histone protein substrates of lysine propionylation in eukaryotic cells: p53, p300, and CREB-binding protein. We used mass spectrometry to map lysine propionylation sites within these three proteins. We also identified the first two in vivo eukaryotic lysine propionyltransferases, p300 and CREB-binding protein, and the first eukaryotic depropionylase, Sirt1. p300 was able to perform autopropionylation on lysine residues in cells. Our results suggest that lysine propionylation, like lysine acetylation, is a dynamic and regulatory post-translational modification. Based on these observations, it appears that some enzymes are common to the lysine propionylation and lysine acetylation regulatory pathways. Our ...
Post-translational modifications (PTMs) play an important role in modulating diverse cellular processes, which are dynamic and reversible modifications of proteins during or after protein biosynthesis [1]. PTMs can change protein functions by introducing new functional groups such as acetyl, phospho, ubiquityl, succinyl and methyl groups. Among these changes, acetylation of lysine has been extensively studied in both eukaryotes and prokaryotes [2, 3]. Similar to lysine acetylation, lysine succinylation is one of the newly discovered PTMs that has been found in both eukaryotes and prokaryotes [1]. As one important PTM of proteins, lysine succinylation was defined as the transfer of a succinyl group to a lysine residue of a protein molecule [4].. Lysine succinylation was firstly discovered in histone proteins, and its role has been investigated in the regulation of gene transcription [5]. In addition to histones, other proteins in the nucleus, cytoplasm and mitochondria were also found to be ...
Lysine acetylation is a conserved, reversible, post-translational protein modification regulated by lysine acetyltransferases (KATs) and lysine deacetylases (KDACs; also known as histone deacetylases (HDACs)) that is involved in many cellular signalling pathways and diseases. Studies in animal models have revealed a regulatory role of reversible lysine acetylation in hypertension, vascular diseases, arrhythmia, heart failure and angiogenesis. Evidence from these studies indicates a therapeutic role of KDAC inhibitors (also known as HDAC inhibitors) in cardiovascular diseases. In this Review, we describe the diverse roles of KATs and KDACs in both the normal and the diseased heart. Among KDACs, class II and class III HDACs seem to have a protective role against both cardiac damage and vessel injury, whereas class I HDACs protect against vessel injury but have deleterious effects on the heart. These observations have important implications for the clinical utility of HDAC inhibitors as therapeutic agents

TP53 (p53) undergoes methylation on several lysine and arginine residues, which modulates its transcriptional activity.. PRMT5, recruited to TP53 as part of the ATM-activated complex that includes TTC5, JMY and EP300 (p300), methylates TP53 arginine residues R333, R335 and R337. PRMT5-mediated methylation promotes TP53-stimulated expression of cell cycle arrest genes (Shikama et al. 1999, Demonacos et al. 2001, Demonacos et al. 2004, Adams et al. 2008, Adams et al. 2012). SETD9 (SET9) methylates TP53 at lysine residue K372, resulting in increased stability and activity of TP53 (Chuikov et al. 2004, Couture et al. 2006, Bai et al. 2011).,p,TP53 transcriptional activity is repressed by SMYD2-mediated methylation of TP53 at lysine residue K370 (Huang et al. 2006). Dimethylation of TP53 at lysine residue K373 by the complex of methyltransferases EHMT1 and EHMT2 also represses TP53-mediated transcription (Huang et al. 2010). The chromatin compaction factor L3MBTL1 binds TP53 monomethylated at lysine ...

were fed the unlabelled diet for 20 d and then the labelled diet for 10 d while wearing a neck collar to avoid caecotrophy (group COLL), in order to discriminate it from direct intestinal absorption. At day 30 animals were slaughtered and caecal bacteria and liver samples taken. The 15N enrichment in amino acids of caecal bacteria and liver were determined by GC-combustion/isotope ratio MS. Lysine showed a higher enrichment in caecal microflora (0·925 atom% excess, APE) than liver (0·215 APE) in group ISOT animals, confirming the double origin of body lysine: microbial and dietary. The COLL group showed a much lower enrichment in tissue lysine (0·007 (SE 0·0029) APE for liver). Any enrichment in the latter animals was due to direct absorption of microbial lysine along the digestive tract, since recycling of microbial protein (caecotrophy) was avoided. In such conditions liver enrichment was low, indicating a small direct intestinal absorption. From the ratio of [15N]lysine enrichment between ...
MAXY-G34 is a pegylated variant of human granulocyte-colony stimulating factor (G-CSF). This variant contains multiple non-naturally occurring lysines that have been introduced into alpha helixes of wild type human G-CSF as PEGylation sites, and from which multiple undesired, naturally occurring lysines have been removed as compared to wild type human G-CSF to avoid PEGylation of such sites. Specifically, the amino acid sequence of MAXY-G34 differs from that of human wild type G-CSF at residues 16, 34, 40, 105 and 159. This was accomplished by removing the three lysine residues at positions 16, 34 and 40, and replacing them with arginine, and substituting two new lysine residues at positions 105 and 159. MAXY-G34 is pegylated with 5 kd mPEG SPA (succinimidyl propionate) groups at 3 amino acid residues, including PEG groups attached at the amino terminal end of the protein and at two internal lysine residues, while Neulasta has a single 20 Kd PEG group attached at the N terminal end of the wild type G

The study was conducted to evaluate the effect of different levels of synthetic lysine (sLys) on dry matter intake (DMI), average daily weight gain (ADG), dry matter conversion ratio (DMCR), carcass characteristics and economics of productionof finisher broiler chicks. As 240 day-old broiler chicks were randomly distributed to 12 pens of 20 chicks each and assigned to four treatment rations in a completely randomized design. Six broilers (3 males and 3 females) from each replication were starved for 16 hours and slaughtered to evaluate carcass characteristics. Control diet had a lysine content of 0.9 and 0.8% of the ration, which was 0.3 and 0.2% of the ration below the recommended level. The four rations were formulated by including sLys at levels of 0, 50, 100 and 150% of the deficient amount of lysine. No sLys in the ration (T1) and rations to which 50% (T2), 100% (T3) and 150% (T4) of the deficient amount of lysine being added as sLys. No significance difference (P|0.05) was observed among

The objectives of this project were to investigate the effects of dietary lysine restriction on (1) the plasma concentrations of selected metabolites, free AAs, and three growth-related hormones, (2) the gene expression profile in longissimus dorsi muscle growing pigs. Twelve individually penned young barrows (Yorkshire × Landrace; 22.6 ± 2.04 kg) were randomly assigned to two dietary treatments (a lysine-deficient, LDD, and a lysineequate, LAD) diets, respectively. Pigs had ad libitum access to water and their respective diets for 8 weeks, and the ADG, ADFI, and G:F were determined. At the end of the trial, jugular vein blood was collected, and plasma was separated for the analysis of plasma parameters. Also, the longissimus dorsi muscle samples were collected from each pig for gene expression profile analysis. The ADG of LDD pigs was lower than that of LAD pigs, and so was the G:F since there was no difference in the ADFI between the two groups of pigs. The plasma concentrations of lysine,

In clinical study, when Lysine hydrochloride (the form it is metabolized best from) is taken in concentrations of less than 1250mg (2 x 625mg tablets) it has a limited effect on the Herpes and cold sore virus - and when taken at a daily dose higher than 3000mg it is shown to be potentially unsafe.. It is important to find the happy medium, which is why the L-Lysine in Combined Lysine Formula is at a specific dose of 625mg of naturally occurring Lysine hydrochloride per tablet (equiv. 500mg of elemental Lysine). This concentration is like this for a reason.. Two 625 mg tablets is equal to the daily recommended dose of Lysine that is shown to retard Herpes in clinical trials. This is the amount you should be taking daily to help prevent outbreaks - its important not to take too much more than this if you are taking it everyday or for a long period of time.. We recommend increasing the dose only when you have active symptoms, like itching, tingling and pain. There is really no benefit in taking ...
To compare expense, we evaluate the metabolizable lysine cost in cents over grams (¢/g). The metabolizable lysine cost of AjiPro®-L is generally 1.6 ¢/g, whereas the price and quality of blood meal vary over time, resulting in a metabolizable lysine cost range of 1.5-3.0 ¢/g. From this perspective, AjiPro®-L generally delivers lysine in a more affordable way compared to blood meal.. Another advantage of AjiPro®-L is its ability to provide consistent, stable quality in the long term. Contrary to the variability in the quality of blood meal, AjiPro®-L delivers a consistent quality and amount of metabolizable lysine. This ensures a predictable, stable income over feed for dairy farmers.. ...
Prokaryotes form ubiquitin (Ub)-like isopeptide bonds on the lysine residues of proteins by at least two distinct pathways that are reversible and regulated. (TtuB tRNA-two-thiouridine B) that differ from Ub in amino acid sequence yet share a common β-grasp fold also form isopeptide bonds by a mechanism that appears streamlined compared with ubiquitylation. SAMPs and TtuB are found to be members of a small group of Ub-fold proteins that function not only in protein modification but also in sulfur-transfer pathways associated with tRNA thiolation and molybdopterin biosynthesis. These multifunctional Ub-fold proteins are thought to be some of the most ancient of Ub-like protein modifiers.

If you choose to supplement your kitty with lysine, there are many cat-friendly lysine treats you can purchase to make getting it into the kitty simple. I am not a fan of most of those due to the nonactive ingredients in them. You can purchase capsules of lysine powder at most stores that sell supplements and open them up and sprinkle it right on your cats regular food. Most cats do not show any signs of noticing when the lysine is added. The recommended dose varies quite a bit, with 250-500mg being suggested as a starting dose for adult cats with some people going up to as high as 1500mg. Splitting the dose throughout the day is more beneficial than giving it just once a day. Kittens should be started at lower doses by half. Eyeballing the dose is perfectly acceptable, so if you buy 500mg capsules, giving 1/4th of it to a kitten per meal should be fine ...

Both plasma and red blood cells contain amino acids (AA), but the relative amount of AA transferred from each vascular compartment to the tissues remains unclear. For splanchnic tissues, the relative transfers between the plasma, the red blood cells and the tissues may vary with nutritional state, but whether the same situation pertains for other tissues is not known. The current study focused on the transfer of lysine from plasma and red blood cells across the hindquarters of sheep offered four levels of intakes (0.5, 1.0, 1.5 and 2.5×maintenance energy). This design, coupled with use of [U-13C]lysine as tracer, also allowed the effect of intake on protein kinetics to be examined. At all intakes, the concentration of lysine in the sheep red blood cells exceeded that in plasma by 50 % (P,0.001), while the distribution of labelled lysine between the plasma and the red blood cells was 0.71:0.29. Net lysine uptake by the hindquarters increased in a linear manner (P,0.001) with intake, with more ...

The two paths of lysine synthesis seem to be quite unusual in the consistency of their dichotomous distribution over a broad range of biological forms. This consistency suggests that these paths did not arise sporadically, and that their distribution pattern was not disturbed by genetic exchange. It appears probable that neither path emerged in an organism possessing the other, since a partial appearance of either path in the presence of the other may well have been selected against, and an appearance in toto is thought unlikely in view of the number of enzymes involved in each path. It is thus assumed that the two lysine paths arose individually in organisms incapable of lysine synthesis ...

Protein therapeutics suffer from low oral bioavailability, mainly due to poor membrane permeability and digestion by gastrointestinal proteases. To improve proteolytic stability, intramolecular thioether crosslinks were introduced into a three-helix affibody molecule binding the human epidermal growth factor receptor (EGFR). Solid-phase peptide synthesis was used to produce an unmodified control protein domain and three different crosslinked protein domain variants: one with a thioether crosslink between the N-terminal lysine residue and a cysteine residue in the second loop region (denoted K4), a second with a crosslink between the C-terminal lysine residue and a cysteine residue in the first loop region (denoted K58), and a third with crosslinks in both positions (denoted K4K58). Circular dichroism (CD) and surface-plasmon-resonance-based (SPR-based) biosensor studies of the protein domains showed that the three-helix structure and high-affinity binding to EGFR were preserved in the ...
Is l lysine safe to take while nursing - Is it safe to take l-lysine while nursing? Ive had been fighting coldsores for 6wks and I have a 7w.o baby. Using abreva. Ice makes it worse. Lysine and nursing. Lysine is an essential amino acid (protein) meaning our body cannot make it. It is part of our diet. We eat 60, 000 mg protein a day. For prophylaxis usually one takes 500-1000 mg a day and for an acute flare I have seen 1500 to 3000 mg/day given for 2-5 days. It may at very high doses interact with arginine another amino acid (but we have to have both in our diet, anyway). Discuss with doc
Short-chain fatty acids and their corresponding acyl-CoAs sit at the crossroads of metabolic pathways and play important roles in diverse cellular processes. They are also precursors for protein post-translational lysine acylation modifications. A noteworthy example is the newly identified lysine 2-hydroxyisobutyrylation (Khib) that is derived from 2-hydroxyisobutyrate and 2-hydroxyisobutyryl-CoA. Histone Khib has been shown to be associated with active gene expression in spermatogenic cells. However, the key elements that regulate this post-translational lysine acylation pathway remain unknown. This has hindered characterization of the mechanisms by which this modification exerts its biological functions. Here we show that Esa1p in budding yeast and its homologue Tip60 in human could add Khib to substrate proteins both in vitro and in vivo. In addition, we have identified HDAC2 and HDAC3 as the major enzymes to remove Khib. Moreover, we report the first global profiling of Khib proteome in mammalian
