Protein

2-methylcitrate dehydratase

Gene

prpD

Organism
Salmonella typhi
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

Involved in the catabolism of short chain fatty acids (SCFA) via the tricarboxylic acid (TCA)(acetyl degradation route) and via the 2-methylcitrate cycle I (propionate degradation route). Catalyzes the stereospecific dehydration of (2S,3S)-2-methylcitrate (2-MC) to yield the cis isomer of 2-methyl-aconitate. Could also catalyze the dehydration of citrate and the hydration of cis-aconitate.By similarity

Catalytic activityi

(2S,3S)-2-hydroxybutane-1,2,3-tricarboxylate = (Z)-but-2-ene-1,2,3-tricarboxylate + H2O.By similarity
Citrate = isocitrate.By similarity

Pathway: propanoate degradation

This protein is involved in the pathway propanoate degradation, which is part of Organic acid metabolism.By similarity
View all proteins of this organism that are known to be involved in the pathway propanoate degradation and in Organic acid metabolism.

Pathway: tricarboxylic acid cycle

This protein is involved in step 2 of the subpathway that synthesizes isocitrate from oxaloacetate.By similarity
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. Citrate synthase (gltA)
  2. Aconitate hydratase B (acnB), Aconitate hydratase B (acnB), 2-methylcitrate dehydratase (prpD), Aconitate hydratase B (acnB)
This subpathway is part of the pathway tricarboxylic acid cycle, which is itself part of Carbohydrate metabolism.
