ID 2.7.7.106 DE 3-phospho-D-glycerate guanylyltransferase. CA (2R)-3-phosphoglycerate + GTP + H(+) = 3-[(R)-glyceryl]-diphospho- CA 5'-guanosine + diphosphate. CC -!- The enzyme, characterized from the Gram-negative bacterium CC Paraburkholderia rhizoxinica, participates in the biosynthesis of CC 3PG-factor 420. CC -!- The enzyme can also accept 2-phospho-L-lactate and CC phosphoenolpyruvate, but activity is much higher with 3-phospho-D- CC glycerate. cf. EC 2.7.7.68 and EC 2.7.7.105.
