WebApr 7, 2024 · The GTPCH2 activity of Rib1 catalyzes the reaction using GTP and water as a substrate to generate its products, which are DARP, formate, and pyrophosphate. Therefore, the effect of each product... GTP 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-NH2-3'-TP). See more GTPCH is encoded by the gene GCH1. Several alternatively spliced transcript variants encoding different isoforms have been described; however, not all of the variants give rise to a functional enzyme. See more At least 94 disease-causing mutations in this gene have been discovered. Mutations in this gene are associated with two disorders: autosomal recessive GTP cyclohydrolase I deficiency See more • Guanosine triphosphate (GTP) • Tetrahydrobiopterin (THB, BH4) • Vitamin B9 (folic acid → folate) See more • GTP+Cyclohydrolase+I at the U.S. National Library of Medicine Medical Subject Headings (MeSH) • GeneReviews/NCBI/NIH/UW entry on GTP Cyclohydrolase 1-Deficient Dopa-Responsive Dystonia See more The transcribed protein is the first and rate-limiting enzyme in tetrahydrobiopterin (THB, BH4) biosynthesis, catalyzing the conversion of GTP into 7,8-DHNP-3'-TP.
