Function
function
(Microbial infection) Catalyzes the phosphorylation of dZDP to dZTP, when the bacterium is infected by a phage that produces the substrate for the synthesis of dZTP (2- amino-2'-deoxyadenosine 5'-triphosphate), which is then used by the phage as a DNA polymerase substrate.
Major role in the synthesis of nucleoside triphosphates other than ATP. The ATP gamma phosphate is transferred to the NDP beta phosphate via a ping-pong mechanism, using a phosphorylated active-site intermediate.
Catalytic activity
- dZDP + ATP = dZTP + ADP
