N-acetylglucosaminyldiphosphoundecaprenol N-acetyl-beta-D-mannosaminyltransferase (, ''uridine diphosphoacetyl-mannosamineacetylglucosaminylpyrophosphorylundecaprenol acetylmannosaminyltransferase'', ''N-acetylmannosaminyltransferase'', ''UDP-N-acetylmannosamine:N-acetylglucosaminyl diphosphorylundecaprenol N-acetylmannosaminyltransferase'', ''UDP-N-acetyl-D-mannosamine:N-acetyl-beta-D-glucosaminyldiphosphoundecaprenol beta-1,4-N-acetylmannosaminyltransferase'') is an
enzyme
Enzymes () are proteins that act as biological catalysts by accelerating chemical reactions. The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products. A ...

This enzyme is involved in the
biosynthesis
Biosynthesis is a multi-step, enzyme-catalyzed process where substrates are converted into more complex products in living organisms. In biosynthesis, simple compounds are modified, converted into other compounds, or joined to form macromolecules. ...
