    This enzyme catalyzes the reversible transamination of branched-chain alpha-keto acids (BCKAs) to the branched-chain amino acids (BCAAs) valine, leucine and isoleucine, which are essential for cell growth. In humans, its primary role is the deamination of BCAAs, as humans lack the enzymes for de novo synthesis of BCKAs.
