Intraphagocytic 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 کاملEmerging Corynebacterium glutamicum systems biology.
Corynebacterium glutamicum is widely used for the biotechnological production of amino acids. Amino acid producing strains have been improved classically by mutagenesis and screening as well as in a rational manner using recombinant DNA technology. Metabolic flux analysis may be viewed as the first systems approach to C. glutamicum physiology since it combines isotope labeling data with metabol...
متن کاملTryptophan-Producing Corynebacterium glutamicum Strain
The aromatic amino acids are synthesized via a common biosynthetic pathway. A tryptophan-producing mutant of Corynebacterium glutamicum was genetically engineered to produce tyrosine or phenylalanine in abundance. To achieve this, three biosynthetic genes encoding the first enzyme in the common pathway, 3-deoxy-D-arabino-heptulosonate 7-phosphate synthase (DS), and the branch-point enzymes chor...
متن کاملAnalysis of the Corynebacterium glutamicum dapA promoter.
Deletion and mutational analysis of the promoter P-dapA from Corynebacterium glutamicum was performed to identify regions and particular nucleotides important for its function. An extended -10 region and a stretch of six T's at positions -55 to -50 were found to be the most important elements in the promoter function. The results of mutational analysis of P-dapA are consistent with the conclusi...
متن کاملCharacterization of methionine export in Corynebacterium glutamicum.
Corynebacterium glutamicum is known for its effective excretion of amino acids under particular metabolic conditions. Concomitant activities of uptake and excretion systems would create an energy-wasting futile cycle; amino acid export systems are therefore tightly regulated. We have used a DNA microarray approach to identify genes for membrane proteins which are overexpressed under conditions ...
