branched-chain amino acid transaminases, BAT1 and BAT2, was
downregulated after amino acid supplementation, with the
exception of BAT1 expression after the addition of leucine. This
result suggests that besides Bat1p and Bat2p, other transaminases
might be involved in the biosynthesis of higher alcohols in amino
acid-supplemented media. For instance, Aro8p and Aro9p, initially
characterised as the aromatic amino acid aminotransferases I and II,
might act as broad-substrate-specificity amino acid transaminases
