CC   -!- FUNCTION: Catalyzes the condensation of pyruvate and acetyl-coenzyme A
CC       to form (R)-citramalate. {ECO:0000255|HAMAP-Rule:MF_01028}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=acetyl-CoA + H2O + pyruvate = (3R)-citramalate + CoA + H(+);
CC         Xref=Rhea:RHEA:19045, ChEBI:CHEBI:15361, ChEBI:CHEBI:15377,

CC         Rule:MF_01028};
CC   -!- PATHWAY: Amino-acid biosynthesis; L-isoleucine biosynthesis; 2-
CC       oxobutanoate from pyruvate: step 1/3. {ECO:0000255|HAMAP-
CC       Rule:MF_01028}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_01028}.
CC   -!- SIMILARITY: Belongs to the alpha-IPM synthase/homocitrate synthase
CC       family. {ECO:0000255|HAMAP-Rule:MF_01028}.
