CC   -!- FUNCTION: Essential for recycling GMP and indirectly, cGMP.
CC       {ECO:0000255|HAMAP-Rule:MF_00328}.
CC   -!- FUNCTION: (Microbial infection) Catalyzes the phosphorylation of dZMP
CC       to dZDP, when the bacterium is infected by a phage that produces the
CC       substrate for the synthesis of dZTP (2- amino-2'-deoxyadenosine 5'-
CC       triphosphate), which is then used by the phage as a DNA polymerase
CC       substrate. {ECO:0000250|UniProtKB:Q9KNM4}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + GMP = ADP + GDP; Xref=Rhea:RHEA:20780,

CC         ChEBI:CHEBI:456216; Evidence={ECO:0000250|UniProtKB:Q9KNM4};
CC   -!- PATHWAY: Purine metabolism. {ECO:0000250|UniProtKB:Q9KNM4}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00328}.
CC   -!- SIMILARITY: Belongs to the guanylate kinase family. {ECO:0000255|HAMAP-
CC       Rule:MF_00328}.
