WebGTP cyclohydrolase I ( GTPCH) ( EC 3.5.4.16) is a member of the GTP cyclohydrolase family of enzymes. GTPCH is part of the folate and biopterin biosynthesis pathways. It is responsible for the hydrolysis of guanosine triphosphate (GTP) to form 7,8-dihydroneopterin triphosphate (7,8-DHNP-3'-TP, 7,8-NH 2 -3'-TP). Gene [ edit] WebFeb 23, 2013 · GTP Cyclohydrolase I (EC 3.5.4.16) The first step of the biosynthesis of drosopterins is catalyzed by GTPCH I, which converts GTP into H 2 -NTP ( 8 ). GTPCH I was first partially purified from the extracts of late pupae and young adults of the species Drosophila melanogaster and characterized by Fan and Brown ( 16) in 1976.
