UDP-N-acetyl-D-glucosamine + [1,4-(N-acetyl-beta-D-glucosaminyl)]n the enzyme itself is capable both of initiating chitin chains without a primer and of determining their length Saccharomyces cerevisiae UDP + [1,4-(N-acetyl-beta-D-glucosaminyl)]n+1 at low concentrations of UDP-GlcNAc, no insoluble chitin is formed. Instead N-acetylglucosamine is incorporated into water-soluble products ?
