CC -!- FUNCTION: Catalyzes the methylation of C-15 in cobalt-precorrin-6B
CC followed by the decarboxylation of C-12 to form cobalt-precorrin-7.
CC {ECO:0000256|HAMAP-Rule:MF_00786}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Co-precorrin-6B + S-adenosyl-L-methionine = Co-precorrin-7 +
CC CO2 + S-adenosyl-L-homocysteine; Xref=Rhea:RHEA:36067,
CC ChEBI:CHEBI:16526, ChEBI:CHEBI:57856, ChEBI:CHEBI:59789,
CC ChEBI:CHEBI:70791, ChEBI:CHEBI:72780; EC=2.1.1.196;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_00786};
CC -!- PATHWAY: Cofactor biosynthesis; adenosylcobalamin biosynthesis;
CC cob(II)yrinate a,c-diamide from sirohydrochlorin (anaerobic route):
CC step 8/10. {ECO:0000256|HAMAP-Rule:MF_00786}.
CC -!- SIMILARITY: Belongs to the methyltransferase superfamily. Archaeal-type
CC CbiT family. {ECO:0000256|HAMAP-Rule:MF_00786}.
