Proteolytic activation and inactivation of chitin synthetase from Mucor rouxii. (1/299)

Crude chitin synthetase preparations from the mycelial and yeast forms of Mucor rouxii behaved differently. The mycelial preparations, incubated at 28 degrees C, lost virtually all chitin synthetase activity in a few hours; by contrast, the activity of enzyme preparations from yeast cells increased several fold during similar incubations. These spontaneous changes were probably caused by endogenous protease(s). Seemingly, the chitin synthetase in yeast preparations was present mainly in a latent, 'zymogenic', form that was activated by proteases. In the mycelial preparations, chitin synthetase was present mainly in an active state and was rapidly degraded by endogenous proteolysis. Exogenous proteases accelerated activation and destruction of chitin synthetase; an acid protease from Rhizopus chinensis was the most effective activator. The activation of chitin synthetase was inhibited by a soluble protein in the cell-free extract. Treatment with the detergent Brij 36T stabilized the chitin synthetase of crude preparations against spontaneous changes. Stabilized preparations were rapidly activated by exogenous proteases. The different behaviour of chitin synthetases in crude extracts of mycelium and yeast cells is consistent with, and perhaps partially responsible for, the differences in wall construction between mycelial and yeast forms of M. rouxii.  (+info)

KNR4, a suppressor of Saccharomyces cerevisiae cwh mutants, is involved in the transcriptional control of chitin synthase genes. (2/299)

The KNR4 gene, originally isolated by complementation of a K9 killer-toxin-resistant mutant displaying reduced levels of both 1,3-beta-glucan and 1,3-beta-glucan synthase activity, was recloned from a YCp50 genomic library as a suppressor of Saccharomyces cerevisiae calcofluor-white-hypersensitive (cwh) mutants. In these mutants, which were characterized by increased chitin levels, the suppressor effect of KNR4 resulted, for some of them, in a lowering of polymer content to close to wild-type level, with no effect on the contents of beta-glucan and mannan. In all cases, this effect was accompanied by a strong reduction in mRNA levels corresponding to CHS1, CHS2 and CHS3, encoding chitin synthases, without affecting expression of FKS1 and RHO1, two genes encoding the catalytic subunit and a regulatory component of 1,3-beta-glucan synthase, respectively. Overexpression of KNR4 also inhibited expression of CHS genes in wild-type strains and in two other cwh mutants, whose sensitivity to calcofluor white was not suppressed by this gene. The physiological relevance of the KNR4 transcriptional effect was addressed in two different ways. In a wild-type strain exposed to alpha-factor, overexpression of this gene inhibited CHS1 induction and delayed shmoo formation, two events which are triggered in response to the pheromone, whereas it did not affect bud formation and cell growth in a chs1 chs2 double mutant. A chimeric protein made by fusing green fluorescent protein to the C terminus of Knr4p which fully complemented a knr4delta mutation was found to localize in patches at presumptive bud sites in unbudded cells and at the incipient bud site during bud emergence. Taken together, these results demonstrate that KNR4 has a regulatory role in chitin deposition and in cell wall assembly. A mechanism by which this gene affects expression of CHS genes is proposed.  (+info)

Chs7p, a new protein involved in the control of protein export from the endoplasmic reticulum that is specifically engaged in the regulation of chitin synthesis in Saccharomyces cerevisiae. (3/299)

The Saccharomyces cerevisiae CHS7 gene encodes an integral membrane protein located in the ER which is directly involved in chitin synthesis through the regulation of chitin synthase III (CSIII) activity. In the absence of CHS7 product, Chs3p, but not other secreted proteins, is retained in the ER, leading to a severe defect in CSIII activity and consequently, to a reduced rate of chitin synthesis. In addition, chs7 null mutants show the yeast phenotypes associated with a lack of chitin: reduced mating efficiency and lack of the chitosan ascospore layer, clear indications of Chs7p function throughout the S. cerevisiae biological cycle. CHS3 overexpression does not lead to increased levels of CSIII because the Chs3p excess is retained in the ER. However, joint overexpression of CHS3 and CHS7 increases the export of Chs3p from the ER and this is accompanied by a concomitant increase in CSIII activity, indicating that the amount of Chs7p is a limiting factor for CSIII activity. Accordingly, CHS7 transcription is increased when elevated amounts of chitin synthesis are detected. These results show that Chs7p forms part of a new mechanism specifically involved in Chs3p export from the ER and consequently, in the regulation of CSIII activity.  (+info)

Proliferation of intrahyphal hyphae caused by disruption of csmA, which encodes a class V chitin synthase with a myosin motor-like domain in Aspergillus nidulans. (4/299)

We have found that the Aspergillus nidulans csmA gene encodes a novel protein which consists of an N-terminal myosin motor-like domain and a C-terminal chitin synthase domain (M. Fujiwara, H. Horiuchi, A. Ohta, and M. Takagi, Biochem. Biophys. Res. Commun. 236:75-78, 1997). To clarify the roles of csmA in fungal morphogenesis, we constructed csmA null mutants. The growth rate of the mutant colonies was almost the same as that of the wild-type strain, but hyphal growth was severely inhibited when a chitin-binding reagent, Calcofluor white or Congo red, was added to the medium. Moreover, morphological abnormalities in tip growth and septum formation were identified microscopically. Proliferation of intracellular new hyphae, called intrahyphal hyphae, which behaved as intrinsic hyphae, was the most striking phenotypic feature among them. These phenotypes were not suppressed when the only chitin synthase domain of csmA was expressed under the control of the alcA promoter, whereas they were suppressed when the intact form of csmA was expressed. Therefore, it was concluded that the product of csmA (CsmA) has important roles in polarized cell wall synthesis and maintenance of cell wall integrity and that the myosin motor-like domain is indispensable for these functions.  (+info)

Differential inhibitory effects of protoberberines on sterol and chitin biosyntheses in Candida albicans. (5/299)

The anti-Candida potentials of 12 Korean medicinal plants were explored: methanol extracts from Coptis rhizoma and Phellodendron amurense caused significant inhibition of growth of Candida albicans, Candida glabrata, Candida krusei and Candida parapsilosis. The predominant active components of the extracts were the protoberberines berberine and palmatine; the most potent inhibition of growth was exhibited by berberine on C. krusei (MIC <4 mg/L) and palmatine on C. parapsilosis (MIC 16 mg/L). Both berberine and palmatine inhibited the in-vivo rate of incorporation of L-[methyl-14C]methionine into C-24 of ergosterol in C. albicans (50% inhibition concentration (IC50 values), 25 microM and 300 microM, respectively); this result suggests that sterol 24-methyl transferase (24-SMT) is one of the cellular targets for the antifungal activity of the protoberberines. In-vitro 24-SMT activity in microsomes from the yeast growth form of C. albicans was inhibited by both berberine (inhibition constant (Ki) 232 microM) and palmatine (Ki 257 microM) in a non-competitive manner; inhibition of 24-SMT was more marked for the mycelial form than for the yeast growth form of this organism. Palmatine inhibited chitin synthase from both the yeast and mycelial growth phases of C. albicans in a non-competitive manner (Ki 780 microM). The effects of protoberberines, extracted from established medicinal plants, on both sterol and cell wall biosyntheses in pathogenic fungi indicate that the potential of these compounds, or their semi-synthetic derivatives, as a novel class of antifungal agents should be investigated more fully.  (+info)

The Candida albicans CHS4 gene complements a Saccharomyces cerevisiae skt5/chs4 mutation and is involved in chitin biosynthesis. (6/299)

The Candida albicans CHS4 gene encoding chitin synthase 4 has been isolated using the Saccharomyces cerevisiae CHS4/SKT5 gene as a probe. The gene contains a 2061 bp open reading frame capable of encoding a protein of 687 amino acids (76053 Da). No intron was observed in the gene. Disruption of CHS4 in C. albicans yielded a Calcofluor-resistant phenotype, indicating that Chs4p contributes to chitin biosynthesis. Consistent with this, overexpression of Chs4p under the regulation of the ScGAL1 promoter enhanced chitin synthase 3 activity in S. cerevisiae 7- to 38-fold. In addition, chs3 and chs4 null mutants were significantly defective in Calcofluor white staining and their chitin content was 10% of that of the parental strain. Chs4p of C. albicans and S. cerevisiae showed 61% identity in the C-terminal half of the proteins and that region of C. albicans Chs4p complemented the Chs4p function of a mutant of S. cerevisiae resistant to Calcofluor white. Therefore, it appears that Chs4p is involved in chitin synthase 3 activity by combining with Chs3p to interact synergistically in chitin biosynthesis.  (+info)

Active site determination of yeast geranylgeranyl protein transferase type I expressed in Escherichia coli. (7/299)

The ram2 and cal1 genes encode the alpha and beta subunits of yeast geranylgeranyl protein transferase type I (GGPT-I), respectively. Arginine 166 of the beta subunit was changed to isoleucine (betaR166I), histidine 216 to aspartic acid (betaH216D), and asparagine 282 to alanine (betaN282A) by sequential PCR using mutagenic primers. The mutants were expressed under the same conditions as the wild-type and were assayed for GGPT-I activity. Wild-type yeast GGPT-I, alphaH145D, alphaD140N, betaR166I, betaH216D and betaN282A mutant GGPT-Is were partially purified by ammonium sulfate fractionation followed by a Q-Sepharose column. Characterization studies were performed using the active fraction of the Q-Sepharose column. In the chemical modification reactions, the catalytic activity of purified enzyme decreased in proportion to the concentration of modifying reagents, such as phenylglyoxal and diethyl pyrocarbonate (DEPC). Geranylgeranyl pyrophosphate (GGPP) protected the enzyme activity from the modification with phenylglyoxal. The measurement of GGPP binding to wild-type and five mutant GGPT-Is was performed by a gel-filtration assay. The binding of GGPP to the betaR166I mutant was low and the Km value for GGPP in the betaR166I mutant increased about 29-fold. Therefore, the results suggest a role for this arginine residue that directly influences the GGPP binding. The activity of the DEPC-modified GGPT-I was inhibited by 80% at 5 mM DEPC. The differential absorption at 242 nm may suggest that at this concentration the modified histidine residues were 1.5 mol per GGPT-I. The protein substrate, glutathione S-transferase fused undecapeptide (GST-CAIL) protected the enzyme from inactivation by DEPC, and the Km value for GST-CAIL in the betaH216D mutant increased about 12-fold. The trypsin digestion of [14C]DEPC-modified enzyme yielded a single radioactive peptide. As a result of the sequence of this radioactive peptide, the histidine 216 residue was assumed to be an essential part of binding of peptide substrate.  (+info)

Chitin synthase III: synthetic lethal mutants and "stress related" chitin synthesis that bypasses the CSD3/CHS6 localization pathway. (8/299)

We screened Saccharomyces strains for mutants that are synthetically lethal with deletion of the major chitin synthase gene CHS3. In addition to finding, not surprisingly, that mutations in major cell wall-related genes such as FKS1 (glucan synthase) and mutations in any of the Golgi glycosylation complex genes (MNN9 family) are lethal in combination with chs3Delta, we found that a mutation in Srv2p, a bifunctional regulatory gene, is notably lethal in the chs3 deletion. In extending studies of fks1-chitin synthase 3 interactions, we made the surprising discovery that deletion of CSD3/CHS6, a gene normally required for Chs3p delivery and activity in vivo, was not lethal with fks1 and, in fact, that lack of Csd3p/Chs6p did not decrease the high level of stress-related chitin made in the fks1 mutant. This finding suggests that "stress response" chitin synthesis proceeds through an alternate Chs3p targeting pathway.  (+info)

Myosin II-dependent contraction of the cytokinetic ring and primary septum formation by chitin synthase II are interdependent processes during cytokinesis in Saccharomyces cerevisiae. Hence, null mutants of myosin II (myo1 Δ) and chitin synthase II (chs2 Δ) share multiple morphological and molecular phenotypes. To understand the nature of their interdependent functions, we will seek to identify genes undergoing transcriptional regulation in chs2 Δ strains and to establish a transcription signature profile for comparison with myo1 Δ strains. A total of 467 genes were commonly regulated between myo1Δ and chs2Δ mutant strains (p ≤ 0.01). Common regulated biological process categories identified by Gene Set Enrichment Analysis (GSEA) in both gene expression profiles were: protein biosynthesis, RNA processing, and stress response. Expression of 17/20 genes in the main transcriptional fingerprint for cell wall stress was confirmed in the chs2Δ strain versus 5/20 for the myo1Δ strain. One of these

Aspergillus fumigatus is an opportunistic fungal pathogen that causes invasive aspergillosis (IA), a life-threatening disease in immunocompromised humans. The echinocandin caspofungin, adopted as a second-line therapy in combating IA, is a β-1,3-glucan synthase inhibitor, which, when used in high concentrations, reverts the anticipated A. fumigatus growth inhibition, a phenomenon called the caspofungin paradoxical effect (CPE). The CPE has been widely associated with increased chitin content in the cell wall due to a compensatory upregulation of chitin synthase-encoding genes. Here, we demonstrate that the CPE is dependent on the cell wall integrity (CWI) mitogen-activated protein kinase MpkAMPK1 and its associated transcription factor (TF) RlmARLM1, which regulate chitin synthase gene expression in response to different concentrations of caspofungin. Furthermore, the calcium- and calcineurin-dependent TF CrzA binds to and regulates the expression of specific chitin synthase genes during the ...
Fungi cause disease in plant and animal hosts. The extent to which virulence determinants are conserved between both classes of pathogens is unknown. We have developed a dual plant-animal infection model based on a single strain of Fusarium oxysporum, the causal agent of vascular wilt disease in plants and an emerging opportunistic pathogen of humans. Injection of microconidia of the well-characterized tomato pathogenic isolate 4287 in the lateral tail vein of immunodepressed mice resulted in disseminated infection of multiple organs and death of the animals. Knockout mutants in genes encoding a Pmk1-type mitogen-activated protein kinase, the pH response transcription factor PacC or a class V chitin synthase, all previously shown to be implicated in virulence on tomato plants, were tested in the disseminated mouse model. Our results indicate that some of these virulence factors play functionally distinct roles during infection of tomato and mice. Thus, a single F. oxysporum strain can be used to ...
Cytokinesis is a crucial event in the cell cycle of all living cells. In fungal cells, it requires co-ordinated contraction of an actomyosin ring and synthesis of both plasmatic membrane and a septum structure that will constitute the new cell wall end. Schizosaccharomyces pombe contains four essential putative (1,3)β-d-glucan synthase catalytic subunits, Bgs1p to Bgs4p. Here we examined the function of Bgs1p in septation by studying the lethal phenotypes of bgs1(+) shut-off and bgs1Delta cells and demonstrated that Bgs1p is responsible and essential for linear (1,3)β-d-glucan and primary septum formation. bgs1(+) shut-off generates a more than 300-fold Bgs1p reduction, but the septa still present large amounts of disorganized linear (1,3)β-d-glucan and partial primary septa. Conversely, both structures are absent in bgs1Delta cells, where there is no Bgs1p. The septum analysis of bgs1(+)-repressed cells indicates that linear (1,3)β-d-glucan is necessary but not sufficient for primary septum ...

First, the Chitin Synthase 3 (CHS3) gene was subcloned out of Saccharomyces Cerevisiae (Bakers Yeast) cDNA (complementary DNA - contains no introns, thus can be used in prokaryotes) with biobrick restriction sites (EcoR1, Xbal1 on one end, and Spe1, Pst1 on the other). CHS3 was chosen as it was found to be the major enzyme (knockouts had 80% reduced Chitin) in its family and requires no co-enzyme or activating compounds. Upon running CHS3 through NEB Cutter V2.0, we found a PST1 restriction site which is incompatible with the biobrick standard (EcoR1, Xbal, Spe1, Pst1). To remove this Pst1 site, we inserted CHS3 into a biobrick vector plasmid, and performed site-directed mutagenesis (SDM). Research revealed that chitin synthase is a transmembrane enzyme, and in order to simulate similar conditions, we decided to use the pMAL vector by NEB which contains a periplasmic membrane signal sequence. CHS3 was subcloned in to the pMAL-p5x NEB vector by first PCRing it out of the biobrick vector plasmid ...

Chitin synthase (CHS), a potential target for eco-friendly insecticides, plays an essential role in chitin formation in insects. In this study, a full-length cDNA encoding chitin synthase 2 (BdCHS2) was cloned and characterized in the oriental fruit fly, Bactrocera dorsalis. The BdCHS2 cDNA had 4417 nucleotides, containing an open reading frame of 4122 nucleotides, which encoded 1373 amino acid residues with a predicted molecular weight of 158.5 kDa. Phylogenetic analysis with other insect CHSs suggested that BdCHS2 belongs to insect CHS2. The BdCHS2 transcript was predominately found in midgut but was detected at low levels in fat body, Malpighian tubules, integument, and trachea. Moreover, BdCHS2 was expressed in all developmental stages, and highly expressed in the feeding stages. There was a positive relationship between BdCHS2 expression and total chitin content during development. Furthermore, both the gene expression and chitin content in midgut decreased when the insect was fed for 24 h, then
Transcriptional regulation of chitin synthases by calcineurin controls paradoxical growth of Aspergillus fumigatus in response to caspofungin.
Though the silencing is not yet 100 percent effective in their study, Zhu said it does leave the mosquitos body with less ability to combat insecticides, which must penetrate the mosquitos exoskeleton. If the gene, called chitin synthase, could be completely silenced, the mosquitoes may die without the use of pesticides because the chitin biosynthesis pathway would be blocked, Zhu said.. Zhu theorized using nanoparticles to deliver dsRNA to mosquito larvae might work because of the low success of manually injecting larvae with dsRNA. Mosquito larvae live in water but because dsRNA quickly dissipates in water, it cant be directly added to the larvaes food source. Zhus group discovered that using nanoparticles assembled from dsRNA facilitates their ingestion by mosquito larvae because the nanoparticles dont dissolve in water. Zhu said the nanoparticles may also stabilize the dsRNA in water.. Now insects will have a much greater likelihood of getting these nanoparticles containing the dsRNA ...

Chitin is abundant in nature due to its compact intractable and inert structure resulted from strong hydrogen bonding network. Chitin is known as one of the second most abundant polysaccharides in nature, after cellulose. In crustaceans, chitin is present in a complex structure with calcium carbonate, forming the rigid skeleton of carapace, shell and tail. In insects, chitin is the main building block of the back plate. This intractable characteristic of chitin is superior in the animal / plant kingdom as protective skeleton but is a major disadvantage for chemical / physical modification. Therefore more efficient methods of reacting or modifying chitin (especially alpha-chitin as it is the most abundant of the 3 types of naturally occurring chitin) is necessary, in order to utilize this biomass as a major renewable raw materials ...

pfam08407 (PSSM ID: 400626): Conserved Protein Domain Family Chitin_synth_1N, This is the N-terminal domain of Chitin synthase (pfam01644)
The structure of chitin was determined by Albert Hofmann in 1929.[3]. Chitin is a modified polysaccharide that contains nitrogen; it is synthesized from units of N-acetyl-D-glucosamine (to be precise, 2-(acetylamino)-2-deoxy-D-glucose). These units form covalent β-(1→4)-linkages (like the linkages between glucose units forming cellulose). Therefore, chitin may be described as cellulose with one hydroxyl group on each monomer replaced with an acetyl amine group. This allows for increased hydrogen bonding between adjacent polymers, giving the chitin-polymer matrix increased strength.. In its pure, unmodified form, chitin is translucent, pliable, resilient, and quite tough. In most arthropods, however, it is often modified, occurring largely as a component of composite materials, such as in sclerotin, a tanned proteinaceous matrix, which forms much of the exoskeleton of insects. Combined with calcium carbonate, as in the shells of crustaceans and molluscs, chitin produces a much stronger ...
Chitin can easily be digested by humans whereas cellulose cannot be digested by humans but a suitable source of fibers. Your body cant digest or absorb fiber. The content is provided for information purposes only. Can Humans Digest Chitin? According to Wikipedia, humans have some ability to digest Could COVID-19 have wiped out the Neandertals? The structure of chitin is most similar to that of cellulose. What they discovered is that while most living primates have only one copy of the CHIA gene, early primates, which tended to be very small, had at least three working copies. Exoskeletons: Exoskeletons are the hard, chitinous coverings on the bodies of arthropods. This dietary fiber is beneficial because it takes longer to digest and reaches further into your colon than most other fiber. Chitin is a structural component of arthropod exoskeletons, fungi cell walls, mollusk shells, and fish scales. Chitin is the second most abundant natural polymer after cellulose.

Chitin and its derivatives-as a potential resource as well as multiple functional substrates-have generated attractive interest in various fields such as biomedical, pharmaceutical, food and environmental industries, since the first isolation of chitin in 1811. Moreover, chitosan and its chitooligosaccharides (COS) are degraded products of chitin through enzymatic and acidic hydrolysis processes; and COS, in particular, is well suited for potential biological application, due to the biocompatibility and nontoxic nature of chitosan. In this review, we investigate the current bioactivities of chitin derivatives, which are all correlated with their biomedical properties. Several new and cutting edge insights here may provide a molecular basis for the mechanism of chitin, and hence may aid its use for medical and pharmaceutical applications.

SCIN - Self-regenerating Chitin INduction Chitin, found in the exoskeletons of insects and crustaceans as well as the cell walls of fungi, is one of the most abundant organic polymers in nature. Like keratin in skin, it comprises the protective outer layer of these organisms. Our goal is to generate a layer of chitin from a lawn of bacteria (Escherichia coli) in response to an external molecular cue. This cue induces chitin synthesis (fast) and cell lysis (slow), allowing for a build-up of chitin followed by cell lysis and subsequent release into the top layer of the lawn. Abrasions expose cells to the external cue for self-repair. This would create a regenerative chitin biolayer with potential medical and industrial applications. ...

Previously, we showed that phagocytosable nonantigenic chitin, a seemingly inert molecule, induces endogenous Th1 cytokines (IL-12, IL-18, TNF-α, IFN-γ) (9, 10, 11). These are cytokines that are generally seen at early stages of infection (innate immunity) caused by intracellular bacteria such as M. bovis BCG (9, 10, 11). Innate immunity is important for protection against intracellular bacterial infections and to induce acquired immunity specific for bacteria (22). It is well established that Th1 cytokines, produced in innate immunity, down-regulate allergic immune (Th2) responses (18). The present study of recall responses clearly shows that allergen-stimulated IL-4, IL-5, and IL-10 production is significantly inhibited by the presence of chitin in the spleen cell cultures (Fig. 1⇑). Our results suggest that IFN-γ produced by NK cells, at least in part, is responsible for the inhibition of the production of these Th2 cytokines.. The provocative findings are that chitin, given orally, ...

In these cells, motor-like proteins called myosins pull against a mesh-like scaffold inside the actin was called from the cell cytoskeleton; this pulling can be thought to press the embryo ODM-201 throughout and lead it to develop longer. Six pieces of cells, operating through the comparative check out the tail, constitute the epidermis of the embryo. Myosin is mainly energetic in two pieces of cells that work along both sides from the embryo. In the pieces above and below these pieces (quite simply, those for the top and lower edges from the worm), the myosins are significantly less energetic. However, it ODM-201 isnt fully realized how this distribution of myosin causes worms to elongate just along the head-to-tail axis. Vuong-Brender et al. have finally mapped the potent makes exerted in the cells from the worms epidermis. The experiments ...
Silkworm pupae meal is a protein-rich feed ingredient with a high nutritional value. Its crude protein content ranges from 50% DM to more than 80% DM (for defatted meal). The lysine (6-7% of the protein) and methionine (2-3% of the protein) contents are particularly high. However, the true protein (calculated as the sum of amino acids) in silkworms was found to correspond to only 73% of the crude protein content (Finke, 2002), which was explained by the presence of chitin, since this component contains nitrogen. However, the chitin content of pupae meal is relatively low, about 3-4% DM (Finke, 2002; Suresh et al., 2012). The presence of chitin and insoluble protein may also explain the presence of fibre, and values of 6-12% DM of ADF have been reported (Finke, 2002; Ioselevich et al., 2004). Undefatted pupae meal is rich in fat, typically in the 20-40% DM range. Defatted meal contains less than 10% oil in the DM. Silkworm oil contains a high percentage of polyunsaturated fatty acids, notably ...

Chitin deacetylase, the enzyme that catalyzes the hydrolysis of acetamido groups of N-acetylglucosamine in chitin, has been purified to homogeneity from mycelial extracts of the fungus Mucor rouxii and further characterized. The enzyme exhibits a low pI (approximately 3). Its apparent molecular mass was determined to be approximately 75 kDa by sodium dodecyl sulfate/polyacrylamide gel electrophoresis and approximately 80 kDa by size-exclusion chromatography, suggesting that the enzyme exists as a monomer. Carbohydrate analysis of purified chitin deacetylase revealed that the enzyme is a high-mannose glycoprotein and that its carbohydrate content is approximately 30% by weight. Chitin deacetylase is active on several chitinous substrates and chitin derivatives. The enzyme requires at least four N-acetylglucosamine residues (chitotetraose) for catalysis, and it is inhibited by carboxylic acids, particularly acetic acid. When glycol chitin (a water-soluble chitin derivative) was used as substrate, ...

Chitin (C8H13O5N)n (/ˈkaɪtɪn/ KY-tin), a long-chain polymer of N-acetylglucosamine, is a derivative of glucose. It is a primary component of cell walls in fungi, the exoskeletons of arthropods, such as crustaceans (e.g., crabs, lobsters and shrimps) and insects, the radulae of molluscs, cephalopod beaks, and the scales of fish and lissamphibians. The structure of chitin is comparable to another polysaccharide - cellulose, forming crystalline nanofibrils or whiskers. In terms of function, it may be compared to the protein keratin. Chitin has proved useful for several medicinal, industrial and biotechnological purposes. The English word chitin comes from the French word chitine, which was derived in 1821 from the Greek word χιτών (chiton), meaning covering. A similar word, chiton, refers to a marine animal with a protective shell. The structure of chitin was determined by Albert Hofmann in 1929. Chitin is a modified polysaccharide that contains nitrogen; it is synthesized from units of ...

The normal considerations (chitin is heavy, so organisms with chitin armor wont get all that big) can be hand-waved away even without resorting to a fantasy setting. Creatures that live underwater can bear greater weight, for example, and in a high-oxygen biome insect-style respiration is easier and operative over larger distances. Even if we dont get organisms on a scale that would allow for breastplate-sized chitin sections, armorers could achieve a lot with chitin scale and layering.. I dont know how useful it would be as large, solid plates in the first place. Even though its a strong barrier, there are lots of practical issues. The biggest one I can think of offhand is that it isnt going to be repairable-- you cant melt it down and reforge it, nor weld on a patch, or anything else. You just have to replace the piece. Scale-style armor doesnt suffer that same drawback, as you can replace damaged sections.. Why bother? (alternatively, it has to be worth it). That isnt meant to be a ...

Tor2 is an activator of the Rom2/Rho1 pathway that regulates α-factor internalization. Since the recruitment of endocytic proteins such as actin binding proteins and the amphiphysins precedes the internalization of α-factor, I hypothesized that loss of Tor function leads to an alteration in the dynamics of the endocytic proteins. I report here that endocytic proteins, Abp1 and Rvs167, are less recruited to endocytic sites not only in tor2 but also tor1 mutants. Furthermore, I found that the endocytic proteins Rvs167 and Sjl2 are completely mistargeted to the cytoplasm in tor1∆tor2ts double mutant cells. I also demonstrate here that the efficiency of endocytic internalization or scission in all tor mutants was drastically decreased. In agreement with the Sjl2 mislocalization, I found that in tor1∆tor2ts double mutant cells, as well as other tor mutant cells, the overall PIP2 level was dramatically increased. Finally, the cell wall chitin content in tor2ts and tor1∆tor2ts mutant cells was also
Despite the economic importance of grasses as food, feed and energy crops, little is known about the genes that control their cell wall synthesis, assembly and remodelling. Here we provide a detailed transcriptome analysis that allowed the identification of genes involved in grass cell wall biogenesis. Differential gene-expression profiling, using maize oligonucleotide arrays, was used to identify genes differentially expressed between an elongating internode, containing cells exhibiting primary cell wall synthesis, and an internode that had just ceased elongation and in which many cells were depositing secondary cell wall material. This is one of only few studies specifically aimed at the identification of cell wall-related genes in grasses. Analysis identified new candidate genes for a role in primary and secondary cell wall-related processes in grasses. The results suggest that many proteins involved in cell wall-related processes during normal development are also recruited during defence-related
p,Biocompatibility, biodegradability, and low cost of chitin and chitosan have drawn immense attention in many fields including medicine, bioinspired material science, pharmaceuticals, and agriculture. Their handling and processing are difficult owing to its insolubility in neutral aqueous solution or organic solvents. One of the methods used to improve the solubility characteristics of chitin and chitosan is chemical modification. Introducing a carboxymethyl group is the most advantageous method of increasing the solubility of chitosan at neutral and alkaline pH. Carboxymethyl chitin (CMC) and carboxymethyl chitosan (CMCS) are water soluble derivatives formed by introducing CH2COOH function into the polymer which endows it with better biological properties. The functional group makes CMC/CMCS nanoparticles (NPs) efficient vehicles for the delivery of DNA, proteins, and drugs. This review provides an overview of the characteristics of CMC/CMCS NPs as well as fulfills the task of describing and ...
Chitin binding appeared to be specific and the authors presented some data that suggested that some of ChtVis-Tomato was stably bound to chitin while some seemed to be continually binding and releasing from chitin.. ChtVis-Tomato was useful for making long time lapse observations in vivo.. The ChtVis-Tomato reporter was construted in the pWALIUM10-moe vector and inserted into the Drosophila genome using phiC31 mediated integration. ChtVis-Tomato is under the regulatory control of a 5XUAS-containing promoter allowing it to be expressed in any Gal4 driver lines of D. melanogaster. The reporter is flanked by gypsy insulator sequences. pWALIUM10-moe contains a mini white gene that serves as a genetic marker in the appropriate mutant white background.. With a bit of modification and reconfiguring ChtVis-Tomato could easily be deployed in any insect and is expected to function as it has in D. melanogaster.. Lukasz F. Sobala, Ying Wang, Paul N. Adler (2015) ChtVis-Tomato, a genetic reporter for in vivo ...

The invention provides a biscuit containing abundant chitin which accounts for 5-8% of the total weight of the biscuit. The weight-losing effect of the chitin is as follows: carboniums in the chitin can be automatically attached to electronegative fat in food so as to block off the action of lipase so that the fat is not absorbed in intestine and is directly discharged out of body, wherein, the chitin is combined with the fat and then is discharged out of body but is not combined with protein in important nutrients, thus preventing harm on a human body. Therefore, the biscuit containing the abundant chitin can be eaten securely by a person who wants to reduce weight without affecting nutrient absorption; and in addition, the chitin is different from the common diet food which reaches the weight-losing effect by suppressing appetite or causing diarrhea of the person, and moreover, the chitin has the efficacy of improving a metabolism function of digestive tract.
Introduction. Chitin is a polysaccharide of animal origin found abundantly in nature and characterized by a fibrous structure. It forms the basis of the main constituent of the outer skeleton of insects and crustaceans like shrimp, crabs and lobster (Kumar et al., 2005). According to Chen (1998) the chitin structure can be modified by removing the acetyl groups, which are bond to amine radicals in the C2 position on the glucan ring, by means of a chemical hydrolysis in concentrated alkaline solution at elevated temperature to produce a deacetylated form known as chitosan.. No, H.K. et al., (2002) stated that antibacterial activity of chitosan is effective in inhibiting growth of bacteria. The antimicrobial properties of chitosan depend on its molecular weight and the type of bacterium. For gram-positive bacteria, chitosan with 470 KDa was the most effective, except for Lactbacillus sp., whereas for gram-negative bacteria, chitosan with 1,106 KDa was effective. Chitosan generally showed stronger ...

The outer body is made up of segments, or rings. Muscles run all along the worm under the segments. Outside of each segment are bristles made of chitin (the same stuff that makes up the exoskeleton of insects). These bristles are like little appendages.
