nucleotide-binding domain (NBD) of ectonucleoside triphosphate diphosphohydrolase 5 (NTPDase5) and similar proteins
NTPDase5 (EC 3.6.1.6), also called nucleoside diphosphate phosphatase ENTPD5, CD39 antigen-like 4 (CD39L4), ER-UDPase, guanosine-diphosphatase ENTPD5, GDPase ENTPD5, inosine diphosphate phosphatase ENTPD5, nucleoside diphosphatase, uridine-diphosphatase ENTPD5, or UDPase ENTPD5, hydrolyzes nucleoside diphosphates with a preference for GDP, IDP and UDP compared to ADP and CDP.
