PF04447dATP/dGTP pyrophosphohydrolase (dATP-dGTP_PPHyd)dATP/dGTP pyrophosphohydrolaseThis domain is found in phage proteins, such as A0A2H5BHG5 from Acinetobacter phage SH-Ab 15497, which are associated with PurZ, an enzyme that catalyses the synthesis of diaminopurine (Z), a DNA modification that gives phages an advantage for evadin ...This domain is found in phage proteins, such as A0A2H5BHG5 from Acinetobacter phage SH-Ab 15497, which are associated with PurZ, an enzyme that catalyses the synthesis of diaminopurine (Z), a DNA modification that gives phages an advantage for evading host restriction enzymes activity [1]. This domain has dATP and dGTP pyrophosphohydrolase activity; it catalyses the hydrolysis of dATP/dGTP to pyrophosphate and dAMP/dGMP, respectively, with little or no activities for NTPs and pyrimidine dNTPs. It is suggested that enzymes containing this domain supply dGMP as the substrate for PurZ, elevating dZTP level to promote Z incorporation [1].
