L-leucine + 2-oxoglutarate = 4-methyl-2-oxopentanoate + L-glutamate
branched-chain amino acid + 2-oxoglutarate = corresponding keto acid + L-glutamate, also acts on L-isoleucine and L-valine. Different from EC 2.6.1.66 valine-pyruvate transaminase

L-leucine + 2-oxoglutarate = 4-methyl-2-oxopentanoate + L-glutamate
bibi ping-pong mechanism. For good 2-oxoacid substrates, release of 2-oxoglutarate is much slower than release of the product amino acid during the transamination reaction

branched-chain-amino-acid:2-oxoglutarate aminotransferase
Also acts on L-isoleucine and L-valine, and thereby differs from EC 2.6.1.6, leucine transaminase, which does not. It also differs from EC 2.6.1.66, valine---pyruvate transaminase.

COMMENTARY
LITERATURE
malfunction
virus-induced gene silencing of BCAT results in abnormal leaf development and loss of apical dominance, suppressed expression of BCAT causes changes in various endogenous hormones and abnormal plant development that can be correlated with transcriptional induction of the KNOX genes, NTH15 and NTH23
physiological function
physiological function
Thermococcus sp. CKU-1 requires L-leucine, L-methionine, L-phenylalanine, L-threonine, L-tryptophan, and L-tyrosine for its growth, which are good substrates for BcAT. The enzyme might be involved in the degradation of these amino acids
physiological function
mutant plants lacking the activities of isoforms bcat3, Bcat4, Bcat6 exhibit a clear macroscopic phenotype with smaller plants and abnormal leaf morphology. The triple mutant shows a dramatic reduction of Met-derived glucosinolate species down to 32 and 14% of wild-type levels in plant foliage and seeds, respectively, accompanied by a 46fold increase of free Met. 5?-Deoxy-5?-methylthioadenosine, an intermediate of the Met recycling pathway, accumulates to relative high amounts in the absence of the cytosolic Bcat4 and Bcat6
physiological function
-
branched-chain aminotransferase yeast mutants exhibit severely compromised target of rapamycin complex TORC1 activity, which is partially restored by expression of isoofrm Bat1 active site mutants, implicating both catalytic and structural roles of branched-chain aminotransferases in TORC1 control. Bat1 interacts with branched-chain amino acid metabolic enzymes and, in a leucine-dependent fashion, with the tricarboxylic acid-cycle enzyme aconitase. Branched-chain aminotransferase mutation perturbs tricarboxylic acid-cycle intermediate levels, consistent with a tricarboxylic acid-cycle block, and results in low ATP levels, activation of AMPK, and TORC1 inhibition
