Protein existence	Evidence at protein level

General annotation (Comments)

Function	Asymmetrically hydrolyzes Ap4p to yield AMP and ATP. Does not hydrolyze Ap2a or Ap6A. Also has an ATPase activity. Was shown to dephosphorylate phosphotyrosine but not phosphoserine or phosphothreonine from phosphorylated peptides. Involved in spore germination by controlling expression of genes coding for gerA and gerK receptors. Ref.3
Catalytic activity	P1,P(4)-bis(5'-guanosyl) tetraphosphate + H2O = GTP + GMP. Ref.2
Cofactor	Nickel. 100-fold less efficiency with manganese. Ref.2
Enzyme regulation	Inhibited by EDTA. HAMAP MF_01443
Subcellular location	Forespore Ref.3.
Sequence similarities	Belongs to the prpE family.
