- GDP-mannose + (phosphomannan)n GMP + (phosphomannan)n+1
Thus, 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. The systematic name of this enzyme class is GDP-mannose:phosphomannan mannose phosphotransferase.
