CC   -!- FUNCTION: Catalyzes the conversion of (8S)-3',8-cyclo-7,8-
CC       dihydroguanosine 5'-triphosphate to cyclic pyranopterin monophosphate
CC       (cPMP). {ECO:0000250|UniProtKB:P0A738}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=(8S)-3',8-cyclo-7,8-dihydroguanosine 5'-triphosphate = cyclic
CC         pyranopterin phosphate + diphosphate; Xref=Rhea:RHEA:49580,
CC         ChEBI:CHEBI:33019, ChEBI:CHEBI:59648, ChEBI:CHEBI:131766;
CC         EC=4.6.1.17; Evidence={ECO:0000250|UniProtKB:P0A738};
CC   -!- PATHWAY: Cofactor biosynthesis; molybdopterin biosynthesis.
CC       {ECO:0000250|UniProtKB:P0A738}.
CC   -!- SUBUNIT: Homohexamer; trimer of dimers. {ECO:0000250|UniProtKB:P0A738}.
CC   -!- MISCELLANEOUS: Seems to be specific for the biogenesis of DMSO
CC       reductase.
CC   -!- SIMILARITY: Belongs to the MoaC family. {ECO:0000305}.
