CIT2 (YCR005C, P08679) notes

• Second functional citrate synthase gene; only cit1 cit2 double mutants are glutamate auxotrophs PMID:3023912.
• Peroxisomal (SKL), glyoxylate cycle PMID:2181273.
• Cryptic N-terminal PTS/MTS PMID:16877773.
• SCF(Ucc1) degrades Cit2p in glucose; oxaloacetate stabilises PMID:25982115; cytoplasmic + peroxisomal [UniProt:P08679].
• Possible methylcitrate synthase activity (cit2 cit3 lacks all MCS activity) PMID:17570335.

Curation: TCA cycle/aerobic respiration/mitochondrial matrix (IBA, RCA) over-annotated for this peroxisomal paralog; core = citrate synthase in glyoxylate cycle (peroxisome, cytosol).
