catalyzes Catalysis () is the process of increasing the rate of a chemical reaction by adding a substance known as a catalyst (). Catalysts are not consumed in the reaction and remain unchanged after it. If the reaction is rapid and the catalyst recyc ...

the chemical reaction :UDP-N-acetyl-beta-D-mannosaminouronate + lipopolysaccharide

\rightleftharpoons

UDP + N-acetyl-beta-D-mannosaminouronosyl-1,4-lipopolysaccharide Thus, the two substrates of this enzyme are UDP-N-acetyl-beta-D-mannosaminouronate and lipopolysaccharide, whereas its two products are UDP and N-acetyl-beta-D-mannosaminouronosyl-1,4-lipopolysaccharide. This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is UDP-N-acetyl-beta-D-mannosaminouronate:lipopolysaccharide N-acetyl-beta-D-mannosaminouronosyltransferase. Other names in common use include ManNAcA transferase, uridine-diphosphoacetylmannosaminuronatetranferase, N-acetylglucosaminylpyrophosphorylundecaprenol glucosyltransferase, and acetylmannosaminuronosyltransferase.
