Standard Gibbs Free Energy of Change Formation (ΔfG in kcal/mol): -97.14094 Inferred by computational analysis [Latendresse, 2013]

Reactions known to consume the compound:

sulfate reduction V (dissimilatory) :
trithionate + bisulfite + a reduced electron acceptor → thiosulfate + 2 bisulfite + an oxidized electron acceptor

Reactions known to produce the compound:

(R)-cysteate degradation , sulfolactate degradation I :
(2R)-3-sulfolactate → pyruvate + bisulfite

sulfolactate degradation III :
L-cysteate + H2O → bisulfite + pyruvate + ammonium

Not in pathways:
3-sulfocatechol + oxygen + H2O → (2E,4Z)-2-hydroxymuconate + bisulfite + 2 H+

Reactions known to both consume and produce the compound:

(R)-cysteate degradation , sulfolactate degradation I , sulfolactate degradation III :
sulfite + H+bisulfite

sulfate reduction V (dissimilatory) :
sulfite + H+bisulfite
trithionate + an oxidized electron acceptor + 2 H2O + OH- ↔ 3 bisulfite + a reduced electron acceptor

In Reactions of unknown directionality:

Not in pathways:
L-cysteate = bisulfite + 2-aminoprop-2-enoate + H+
a [SoxY protein]-L-cysteine + bisulfite = [a SoxY protein]-L-cysteine-S-sulfinate + H2O

Enzymes inhibited by bisulfite, sorted by the type of inhibition, are:

Inhibitor (Competitive) of: nitrite reductase [Lafferty74]
