WebThis enzyme belongs to the family of hydrolases, specifically those acting on triphosphoric monoester bonds. The systematic name is dGTP triphosphohydrolase. Other names in common use include deoxy-GTPase, deoxyguanosine 5-triphosphate triphosphohydrolase, deoxyguanosine triphosphatase, and deoxyguanosine triphosphate triphosphohydrolase. WebDeoxyribonucleoside triphosphate triphosphohydrolase from Thermus thermophilus (Tt-dNTPase) has a unique regulatory mechanism for the degradation of deoxyribonucleoside triphosphates (dNTPs). Whereas the Escherichia coli homologue specifically hydrolyzes dGTP alone, dNTPs act as both substrate and activator for Tt-dNTPase. WebSep 9, 2024 · Deoxyribonucleotide triphosphates (dNTPs) are the precursors of DNA synthesis, and their strict balance is critical for proper DNA replication and repair in cells [1]. When cells proliferate, the availability of dNTP fluctuate: the largest pools are seen during S phase and the smallest in G0, which controls the initiation of DNA replication [2]. houzecrushers
