CC   -!- FUNCTION: Guanylyltransferase that catalyzes the activation of
CC       phosphoenolpyruvate (PEP) as enolpyruvoyl-2-diphospho-5'-guanosine, via
CC       the condensation of PEP 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=GTP + H(+) + phosphoenolpyruvate = diphosphate + enolpyruvoyl-
CC         2-diphospho-5'-guanosine; Xref=Rhea:RHEA:30519, ChEBI:CHEBI:15378,
CC         ChEBI:CHEBI:33019, ChEBI:CHEBI:37565, ChEBI:CHEBI:58702,
CC         ChEBI:CHEBI:143701; EC=2.7.7.105; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_02114};
CC   -!- PATHWAY: Cofactor biosynthesis; coenzyme F420 biosynthesis.
CC       {ECO:0000255|HAMAP-Rule:MF_02114}.
CC   -!- MISCELLANEOUS: The exact nature of the substrate is currently not
CC       known. This entry has been annotated based on its similarity to
CC       Actinobacteria. {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the CofC family. {ECO:0000255|HAMAP-
CC       Rule:MF_02114}.
