CC -!- FUNCTION: Catalyzes the carbon skeleton rearrangement of L-glutamate to
CC L-threo-3-methylaspartate ((2S,3S)-3-methylaspartate).
CC {ECO:0000255|HAMAP-Rule:MF_00526}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(2S,3S)-3-methyl-L-aspartate = L-glutamate;
CC Xref=Rhea:RHEA:12857, ChEBI:CHEBI:29985, ChEBI:CHEBI:58724;
CC EC=5.4.99.1; Evidence={ECO:0000255|HAMAP-Rule:MF_00526};
CC -!- COFACTOR:
CC Name=adenosylcob(III)alamin; Xref=ChEBI:CHEBI:18408;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00526};
CC -!- PATHWAY: Amino-acid degradation; L-glutamate degradation via mesaconate
CC pathway; acetate and pyruvate from L-glutamate: step 1/4.
CC {ECO:0000255|HAMAP-Rule:MF_00526}.
CC -!- SUBUNIT: Heterotetramer composed of 2 epsilon subunits (GlmE) and 2
CC sigma subunits (GlmS). GlmE exists as a homodimer and GlmS as a
CC monomer. {ECO:0000255|HAMAP-Rule:MF_00526}.
CC -!- SIMILARITY: Belongs to the methylaspartate mutase GlmS subunit family.
CC {ECO:0000255|HAMAP-Rule:MF_00526}.
