== Function ==
[https://www.uniprot.org/uniprot/BCAT1_HUMAN BCAT1_HUMAN] Catalyzes the first reaction in the catabolism of the essential branched chain amino acids leucine, isoleucine, and valine.

== Publication Abstract from PubMed ==
The branched-chain amino acid transaminases (BCATs) are enzymes that catalyze the first reaction of catabolism of the essential branched-chain amino acids to branched-chain keto acids to form glutamate. They are known to play a key role in different cancer types. Here, we report a new structural class of BCAT1/2 inhibitors, (trifluoromethyl)pyrimidinediones, identified by a high-throughput screening campaign and subsequent optimization guided by a series of X-ray crystal structures. Our potent dual BCAT1/2 inhibitor BAY-069 displays high cellular activity and very good selectivity. Along with a negative control (BAY-771), BAY-069 was donated as a chemical probe to the Structural Genomics Consortium.
