Synthesis of 1,3#-Glucanase and P-N-Acetylglucosaminidase during Autolysis of Neurospora crassa
The synthesis of 1,3-P-glucanase, P-N-acetylglucosaminidase and total protein was studied during autolysis of Neurospora crassa. Evidence for de novo protein synthesis during autolysis was obtained from the incorporation of [3H]tryptophan and [3H]phenylalanine into the protein pool and from the inhibitory effects of cycloheximide and puromycin. Glucose accumulated in the growth medium during au...
متن کاملIntraphagocytic Β-n-acetylglucosaminidase
The beta-N-acetylglucosaminidases of rabbit and human polymorphonuclear leukocytes and of rabbit alveolar macrophages have been studied in comparison with the beta-N-acetylglucosaminidase derived from a soil bacillus which had previously been shown to hydrolyze the group-specific polysaccharide of Group A streptococci. The phagocytic enzymes are lysosome associated and have an acid pH optimum. ...
متن کاملAn acidic, thermostable exochitinase with β-N-acetylglucosaminidase activity from Paenibacillus barengoltzii converting chitin to N-acetyl glucosamine
BACKGROUND N-acetyl-β-D-glucosamine (GlcNAc) is widely used as a valuable pharmacological agent and a functional food additive. The traditional chemical process for GlcNAc production has some problems such as high production cost, low yield, and acidic pollution. Hence, to identify a novel chitinase that is suitable for bioconversion of chitin to GlcNAc is of great value. RESULTS A novel chit...
متن کاملMolecular characterization of an intracellular beta-N-acetylglucosaminidase involved in the chitin degradation system of Streptomyces thermoviolaceus OPC-520.
We purified and characterized an intracellular beta-N-acetylglucosaminidase (NagC) from a cytoplasmic fraction of Streptomyces thermoviolaceus OPC-520. The molecular mass of NagC was estimated to be 60 kDa by SDS-polyacrylamide gel electrophoresis (SDS-PAGE). The optimum pH and temperature of the enzyme were 6.0 and 50 degrees C respectively. Purified NagC hydrolyzed chitin oligosaccharides fro...
متن کاملShort-Chain Chitin Oligomers: Promoters of Plant Growth
Chitin is the second most abundant biopolymer in nature after cellulose, and it forms an integral part of insect exoskeletons, crustacean shells, krill and the cell walls of fungal spores, where it is present as a high-molecular-weight molecule. In this study, we showed that a chitin oligosaccharide of lower molecular weight (tetramer) induced genes in Arabidopsis that are principally related t...
