Enzyme Information

2.7.7.68

2-phospho-L-lactate guanylyltransferase.

based on mapping to UniProt Q8PU52

(2S)-2-phospholactate + GTP = (2S)-lactyl-2-diphospho-5'-guanosine + diphosphate.

-!- This enzyme is involved in the biosynthesis of coenzyme F420, a redox-active cofactor found in all methanogenic archaea, as well as some eubacteria.
