CC   -!- FUNCTION: Protein-lysine methyltransferase that selectively
CC       trimethylates citrate synthase (CS) in mitochondria. Seems to conduct
CC       trimethylation in a highly distributive manner rather than in a
CC       processive manner, and thus introduces a single methyl group per
CC       binding event. {ECO:0000250|UniProtKB:A8MUP2}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=L-lysyl-[citrate synthase] + S-adenosyl-L-methionine = H(+) +
CC         N(6)-methyl-L-lysyl-[citrate synthase] + S-adenosyl-L-homocysteine;

CC   -!- ACTIVITY REGULATION: Citrate synthase-lysine methyltransferase activity
CC       is inhibited by S-adenosylhomocysteine (AdoHcy) and oxaloacetate (OAA).
CC       {ECO:0000250|UniProtKB:A8MUP2}.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion {ECO:0000250|UniProtKB:A8MUP2}.
CC   -!- SIMILARITY: Belongs to the methyltransferase superfamily.
