L-Valine (→) Transport: [Bacteroides] pectinophilus ATCC 43243, Cytosol to [Bacteroides] pectinophilus ATCC 43243, Periplasmic Space
Hydrogen Ion + 2 Pyruvic acid → (S)-2-Acetolactate + Carbon dioxide
Isovaleric acid + L-Glutamic acid → L-Valine + Oxoglutaric acid
(S)-2-Acetolactate + Hydrogen Ion + NADPH → (R)-2,3-Dihydroxy-isovalerate + NADP
(R)-2,3-Dihydroxy-isovalerate → Isovaleric acid + Water
