                    | UPA00626 | (R,R)-butane-2,3-diol biosynthesis~In some bacteria, pyruvate can be channeled via alpha-acetolactate into neutral compound 2,3-butanediol. The production of (R,R)-2,3-butanediol is enhanced when oxygen is limited and the pH is lowered. | None - {{∅}} | None - {{∅}} | Unexplained |  |
