CC   -!- PATHWAY: Carbohydrate metabolism; tricarboxylic acid cycle; isocitrate
CC       from oxaloacetate: step 1/2.
CC   -!- MISCELLANEOUS: Citrate synthase is found in nearly all cells capable of
CC       oxidative metabolism.
CC   -!- SIMILARITY: Belongs to the citrate synthase family. {ECO:0000305}.
