deoxynucleoside triphosphate triphosphohydrolase SAMHD1 M-CSA #994 | Sterile α-motif/histidine-aspartate domain-containing protein (SAMHD1) is a homo-tetrameric GTP/dGTP-activated dNTPase which catalyses the conversion of dNTP into 2'-deoxynucleoside and triphosphate. The enzyme interconverts between an inactive monomeric or dimeric form and a dGTP/GTP-induced active tetrameric form. SAMHD1 is ubiquitously expressed in various human organs. | Defined by 12 residues: GLN:A-73 [auth A-149]HIS:A-91 [auth A-167]HIS:A-130 [auth A-206]ASP:A-131 [auth A-207]HIS:A-134 [auth A-210]HIS:A-139 [auth A-215]ASP:A-142 [auth A-218]HIS:A-157 [auth A-233]ASP:A-235 [auth A-311]LYS:A-236 [auth A-312]ASP:A-243 [auth A-319]ARG:A-290 [auth A-366] | EC: 3.1.5 (PDB Primary Data) |
