In enzymology a phosphomannan mannosephosphotransferase (EC 2.7.8.9) is an enzyme that catalyzes the chemical reactionGDP-mannose + (phosphomannan)n GMP + (phosphomannan)n+1Thus the two substrates of this enzyme are GDP-mannose and (phosphomannan)n whereas its two products are GMP and (phosphomannan)n+1.This enzyme belongs to the family of transferases specifically those transferring non-standard substituted phosphate groups.
