Reaction: 3-phospho-D-glycerate + GTP = 3-(D-glyceryl)-diphospho-5'-guanosine + diphosphate
Other name(s): cofC (gene name) (ambiguous)
Systematic name: GTP:3-phospho-D-glycerate guanylyltransferase
Comments: The enzyme, characterized from the Gram-negative bacterium Paraburkholderia rhizoxinica, participates in the biosynthesis of 3PG-factor 420. The enzyme can also accept 2-phospho-L-lactate and phosphoenolpyruvate, but activity is much higher with 3-phospho-D-glycerate. cf. EC 22.214.171.124, 2-phospho-L-lactate guanylyltransferase and EC 126.96.36.199, phosphoenolpyruvate guanylyltransferase.
