CC -!- FUNCTION: Catalyzes the reversible interconversion of isobutyryl-CoA
CC and n-butyryl-CoA, using radical chemistry. Also exhibits GTPase
CC activity, associated with its G-protein domain (MeaI) that functions as
CC a chaperone that assists cofactor delivery and proper holo-enzyme
CC assembly. {ECO:0000256|HAMAP-Rule:MF_02050}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2-methylpropanoyl-CoA = butanoyl-CoA; Xref=Rhea:RHEA:13141,
CC ChEBI:CHEBI:57338, ChEBI:CHEBI:57371; EC=5.4.99.13;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_02050};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=GTP + H2O = GDP + H(+) + phosphate; Xref=Rhea:RHEA:19669,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:37565,
CC ChEBI:CHEBI:43474, ChEBI:CHEBI:58189; Evidence={ECO:0000256|HAMAP-
CC Rule:MF_02050};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_02050};
CC -!- COFACTOR:
CC Name=adenosylcob(III)alamin; Xref=ChEBI:CHEBI:18408;
CC Evidence={ECO:0000256|ARBA:ARBA00001922,
CC ECO:0000256|HAMAP-Rule:MF_02050};
CC -!- SUBUNIT: Homodimer. {ECO:0000256|HAMAP-Rule:MF_02050}.
CC -!- DOMAIN: Is composed of four functional domains: the N-terminal 5'-
CC deoxyadenosylcobalamin binding region that is homologous to the small
CC subunit of ICM (IcmB), a middle P-loop GTPase domain (MeaI) that likely
CC acts as a chaperone for ICM, a structured linker region involved in
CC dimer formation, and a C-terminal part that is homologous to the large
CC substrate-binding subunit of ICM (IcmA). {ECO:0000256|HAMAP-
CC Rule:MF_02050}.
CC -!- SIMILARITY: Belongs to the IcmF family. {ECO:0000256|HAMAP-
CC Rule:MF_02050}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_02050}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
