About This Section
| Entrez Gene summary for GCH1: This gene encodes a member of the GTP cyclohydrolase family. The encoded protein is the first and rate-limiting enzymein tetrahydrobiopterin (BH4) biosynthesis, catalyzing the conversion of GTP into 7,8-dihydroneopterin triphosphate.BH4 is an essential cofactor required by aromatic amino acid hydroxylases as well as nitric oxide synthases. Mutationsin this gene are associated with malignant hyperphenylalaninemia and dopa-responsive dystonia. Several alternativelyspliced transcript variants encoding different isoforms have been described; however, not all variants give rise to afunctional enzyme. (provided by RefSeq, Jul 2008) UniProtKB/Swiss-Prot: GCH1_HUMAN, P30793Function: Positively regulates nitric oxide synthesis in umbilical vein endothelial cells (HUVECs). May be involved indopamine synthesis. May modify pain sensitivity and persistence. Isoform GCH-1 is the functional enzyme, the potentialfunction of the enzymatically inactive isoforms remains unknown Gene Wiki entry for GCH1 (GTP cyclohydrolase I)

About This Section
| Function Summary: UniProtKB/Swiss-Prot: GCH1_HUMAN, P30793Function: Positively regulates nitric oxide synthesis in umbilical vein endothelial cells (HUVECs). May be involved indopamine synthesis. May modify pain sensitivity and persistence. Isoform GCH-1 is the functional enzyme, the potentialfunction of the enzymatically inactive isoforms remains unknownCatalytic activity: GTP + H(2)O = formate + 2-amino-4-hydroxy-6-(erythro-1,2,3-trihydroxypropyl)-dihydropteridinetriphosphateEnzyme regulation: GTP shows a positive allosteric effect, and tetrahydrobiopterin inhibits the enzyme activity. Zincis required for catalytic activity. Inhibited by Mg(2+)Biophysicochemical properties: Kinetic parameters: KM=116 uM for GTP; pH dependence: Optimum pH is 7.7 in phosphatebuffer; Temperature dependence: Relatively stable at high temperatures. Retains 50% of its activity after incubationat 70 degrees Celsius for 15 minutes;Induction: Up-regulated by IFNG/IFN-gamma, TNF, IL1B/interleukin-1 beta, bacterial lipopolysaccharides (LPS) andphenylalanine, and down-regulated by dibutyryl-cAMP, iloprost and 8-bromo-cGMP in HUVEC cells. Up-regulation of GCH1expression, in turn, stimulates production of tetrahydrobiopterin, with subsequent elevation of endothelial nitricoxide synthase activity. Cytokine-induced GCH1 up-regulation in HUVECs in response to TNF and IFNG/IFN-gamma involvescooperative activation of both the NF-kappa-B and JAK2/STAT pathways. Also up-regulated by hydrogen peroxide in humanaorta endothelial cells (HAECs) Genatlas biochemistry entry for GCH1:GTP cyclohydrolase I,catalyzing the first step of tetrahydrobiopterin (BH4) synthesis Enzyme Number (IUBMB): EC 3.5.4.161 2

Defects in GCH1 are the cause of GTP cyclohydrolase 1 deficiency (GCH1D) [MIM:233910]; also known as atypicalsevere phenylketonuria due to GTP cyclohydrolase I deficiency;. GCH1D is one of the causes of malignanthyperphenylalaninemia due to tetrahydrobiopterin deficiency. It is also responsible for defective neurotransmissiondue to depletion of the neurotransmitters dopamine and serotonin. The principal symptoms include: psychomotorretardation, tonicity disorders, convulsions, drowsiness, irritability, abnormal movements, hyperthermia,hypersalivation, and difficulty swallowing. Some patients may present a phenotype of intermediate severity betweensevere hyperphenylalaninemia and mild dystonia type 5 (dystonia-parkinsonism with diurnal fluctuation). In thisintermediate phenotype, there is marked motor delay, but no mental retardation and only minimal, if any,hyperphenylalaninemia Defects in GCH1 are the cause of dystonia type 5 (DYT5) [MIM:128230]; also known as progressive dystonia withdiurnal fluctuation, autosomal dominant Segawa syndrome or dystonia-parkinsonism with diurnal fluctuation. DYT5 is aDOPA-responsive dystonia. Dystonia is defined by the presence of sustained involuntary muscle contractions, oftenleading to abnormal postures. DYT5 typically presents in childhood with walking problems due to dystonia of the lowerlimbs and worsening of the dystonia towards the evening. It is characterized by postural and motor disturbancesshowing marked diurnal fluctuation. Torsion of the trunk is unusual. Symptoms are alleviated after sleep andaggravated by fatigue and excercise. There is a favorable response to L-DOPA without side effects 20/62 diseases for GCH1 (see all 62): About MalaCardsdopa-responsive dystonia gtp cyclohydrolase 1-deficient dopa-responsive dystonia dystonia, dopa-responsive, with or without hyperphenylalainemia gtp cyclohydrolase i deficiency hyperphenylalaninemia biotin-responsive basal ganglia disease dystonia musculorum deformans tyrosine hydroxylase deficiency torsion dystonia myoclonus-dystonia hermansky-pudlak syndrome complex regional pain syndrome degenerative disc disease basal ganglia disease back pain segawa syndrome tetrahydrobiopterin deficiency somatoform disorder spastic paraplegia essential tremor
