Branched chain amino acid transaminase 1 is a protein that in humans is encoded by the BCAT1 gene. It is the first enzyme in the branched-chain amino acid (BCAA) degradation pathway and facilitates the reversible transamination of BCAAs and glutamate. BCAT1 resides in the cytoplasm, while its isoform, BCAT2, is found in the mitochondria.
