CC   -!- FUNCTION: Guanylyltransferase that catalyzes the activation of (2S)-2-
CC       phospholactate (2-PL) as (2S)-lactyl-2-diphospho-5'-guanosine, via the
CC       condensation of 2-PL with GTP. It is involved in the biosynthesis of
CC       coenzyme F420, a hydride carrier cofactor. {ECO:0000255|HAMAP-
CC       Rule:MF_02114}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=(2S)-2-phospholactate + GTP + H(+) = (2S)-lactyl-2-diphospho-
CC         5'-guanosine + diphosphate; Xref=Rhea:RHEA:63424, ChEBI:CHEBI:15378,

CC         Rule:MF_02114};
CC   -!- PATHWAY: Cofactor biosynthesis; coenzyme F420 biosynthesis.
CC       {ECO:0000255|HAMAP-Rule:MF_02114}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_02114}.
CC   -!- SIMILARITY: Belongs to the CofC family. {ECO:0000255|HAMAP-
CC       Rule:MF_02114}.
