This pathway demonstrates the biosynthesis of tetrahydromonapterin in E.coli. However, it is still unclear about biological role of tetrahydromonapterin. GTP cyclohydrolase 1 generates formic acid and 7,8-dihydroneopterin 3'-triphosphate with cofactor GTP and water. 7,8-dihydroneopterin 3'-triphosphate is converted to dihydromonapterin-triphosphate by d-erythro-7,8-dihydroneopterin triphosphate epimerase (folX). Later, dihydromonapterin-triphosphate is hydroxylated to dihydromethysticin, and eventually form tetrahydromonapterin via dihydromonapterin reductase (folM) with cofactor NADPH.
