CC   -!- FUNCTION: Catalyzes the interconversion of succinyl-CoA and
CC       methylmalonyl-CoA. Could be part of a pathway that converts succinate
CC       to propionate. {ECO:0000269|PubMed:10769117,
CC       ECO:0000269|PubMed:11955068}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=(R)-methylmalonyl-CoA = succinyl-CoA; Xref=Rhea:RHEA:22888,
