Characterization of the guanosine 5'-triphosphate 3'-diphosphate and guanosine 5'-diphosphate 3'-diphosphate degradation reaction catalyzed by a specific pyrophosphorylase from Escherichia coli.
Heinemeyer E.A., Richter D.
Guanosine 5'-triphosphate 3'-diphosphate (pppGpp) and guanosine 5'-diphosphate 3'-diphosphate (ppGpp) are specifically degraded by a manganese-dependent pyrophosphorylase present in spoT+ but not in spoT-strains of Escherichia coli, indicating that the enzyme is the spoT gene product.

Guanosine 5'-triphosphate 3'-diphosphate (pppGpp) and guanosine 5'-diphosphate 3'-diphosphate (ppGpp) are specifically degraded by a manganese-dependent pyrophosphorylase present in spoT+ but not in spoT-strains of Escherichia coli, indicating that the enzyme is the spoT gene product. The enzyme catalyzes the release of pyrophosphate from the 3' position of ppGpp or pppGpp, yielding ppG and pppG, respectively; pppGpp could not be detected as an intermediate in the decay reaction. Degradation of (p)ppGpp is optimal in the presence of 200 to 300 mM potassium or sodium acetate, at a pH of 7.5 to 8 and a temperature of 37 degrees C. << Less
