Function

PXPB_BACSU Catalyzes the cleavage of 5-oxoproline to form L-glutamate coupled to the hydrolysis of ATP to ADP and inorganic phosphate (PubMed:28830929). In addition, is a potent inhibitor of the autophosphorylation reaction of kinase A (kinA) and its reverse reaction, but does not inhibit phosphate transfer to the Spo0F response regulator once kinase A is phosphorylated. Is an inhibitor of the catalytic domain of kinase A affecting the ATP/ADP reactions and not the phosphotransferase functions of this domain. The inhibition is non-competitive with respect to ATP (PubMed:9334321).^[1] ^[2]
