Chitin metabolism
WebChitin synthesis is directly governed by an enzymatic activity called chitin synthase (CS). The use of the budding yeast Saccharomyces cerevisiae as a biological model allowed the identification of three distinct chitin synthase activities: CSI, involved in repair functions at the end of cytokinesis; CSII, responsible for the synthesis of the ... WebAbstract. Actinobacteria, a large group of Gram-positive bacteria, secrete a wide range of extracellular enzymes involved in the degradation of organic compounds and biopolymers including the ubiquitous aminopolysaccharides chitin and chitosan. While chitinolytic enzymes are distributed in all kingdoms of life, actinobacteria are recognized as ...
