Chitin synthetase

In enzymology, a chitin synthase (EC 2.4.1.16) is an enzyme that catalyzes the chemical reaction UDP-N-acetyl-D-glucosamine + [1,4-(N-acetyl-beta-D-glucosaminyl)]n UDP + [1,4-(N-acetyl-beta-D-glucosaminyl)]n 1 Thus, the two substrates of this enzyme are UDP-N-acetyl-D-glucosamine and [[[1,4-(N-acetyl-beta-D-glucosaminyl)]n]], whereas its two products are UDP and [[[1,4-(N-acetyl-beta-D-glucosaminyl)]… WebCHITIN SYNTHETASE ACTIVITY IN CELL-FREE EXTRACTS OJI' P. cridania• Stage of development Radioactivity Incorporated Percentage into pellet Incorporation of (d.p.m./mg N) "C into pellet ...
