CC   -!- FUNCTION: Catalyzes the methylation of C-1 in cobalt-precorrin-5B to
CC       form cobalt-precorrin-6A. {ECO:0000255|HAMAP-Rule:MF_00787}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Co-precorrin-5B + S-adenosyl-L-methionine = Co-precorrin-6A +
CC         S-adenosyl-L-homocysteine; Xref=Rhea:RHEA:26285, ChEBI:CHEBI:57856,

CC         EC=2.1.1.195; Evidence={ECO:0000255|HAMAP-Rule:MF_00787};
CC   -!- PATHWAY: Cofactor biosynthesis; adenosylcobalamin biosynthesis;
CC       cob(II)yrinate a,c-diamide from sirohydrochlorin (anaerobic route):
CC       step 6/10. {ECO:0000255|HAMAP-Rule:MF_00787}.
CC   -!- SIMILARITY: Belongs to the CbiD family. {ECO:0000255|HAMAP-
CC       Rule:MF_00787}.
