Branched-chain-amino-acid aminotransferase
Hydrogen Ion + 2 Pyruvic acid → (S)-2-Acetolactate + Carbon dioxide
Isovaleric acid + L-Glutamic acid → L-Valine + Oxoglutaric acid
(R)-2,3-Dihydroxy-isovalerate → Isovaleric acid + Water
(S)-2-Acetolactate + Hydrogen Ion + NADPH → (R)-2,3-Dihydroxy-isovalerate + NADP
L-Valine (→) Transport: Desulfovibrio piger ATCC 29098, Cytosol to Desulfovibrio piger ATCC 29098, Periplasmic Space
