In enzymology a GDP-mannose 46-dehydratase (EC 4.2.1.47) is an mannosyltransferase enzyme that catalyzes the chemical reactionGDP-mannose GDP-4-dehydro-6-deoxy-D-mannose + H2OHence this enzyme has one substrate GDP-mannose and two products GDP-4-dehydro-6-deoxy-D-mannose and H2O.This enzyme belongs to the family of lyases specifically the hydro-lyases which cleave carbon-oxygen bonds.
