WebChitinase 3-like 1 (CHI3L1), also known as YKL-40, is a secreted glycoprotein member of the glycoside hydrolase 18 chitinase family that targets chitin but lacks enzymatic activity (Renkema et al., 1998 ). Although its physiologic function remains unknown, recent studies support a clear prognostic role for CHI3L1 in MS. WebThis article compiles the papers dealing with the biochemistry of chitin synthase (CS) published during the last decade, provides up-to-date information on the state of knowledge and understanding of chitin synthesis in vitro, and points out some firmly entrenched ideas and tenets of CS biochemistry … Biochemistry of chitin synthase EXS.
