CC -!- FUNCTION: Involved in the glycolate utilization. Catalyzes the
CC condensation and subsequent hydrolysis of acetyl-coenzyme A (acetyl-
CC CoA) and glyoxylate to form malate and CoA. {ECO:0000256|HAMAP-
CC Rule:MF_00641}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=acetyl-CoA + glyoxylate + H2O = (S)-malate + CoA + H(+);
CC Xref=Rhea:RHEA:18181, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,

CC ChEBI:CHEBI:57288; EC=2.3.3.9;
CC Evidence={ECO:0000256|ARBA:ARBA00001699, ECO:0000256|HAMAP-
CC Rule:MF_00641, ECO:0000256|RuleBase:RU003572};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000256|ARBA:ARBA00001946,
CC ECO:0000256|HAMAP-Rule:MF_00641};
CC -!- PATHWAY: Carbohydrate metabolism; glyoxylate cycle; (S)-malate from
CC isocitrate: step 2/2. {ECO:0000256|HAMAP-Rule:MF_00641,
CC ECO:0000256|RuleBase:RU003572}.
CC -!- SUBUNIT: Monomer. {ECO:0000256|HAMAP-Rule:MF_00641}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00641,
CC ECO:0000256|RuleBase:RU003572}.
CC -!- SIMILARITY: Belongs to the malate synthase family. GlcB subfamily.
CC {ECO:0000256|HAMAP-Rule:MF_00641, ECO:0000256|RuleBase:RU003572}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_00641}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
