Protein

Aldehyde dehydrogenase PuuC

Gene

puuC

Organism
Escherichia coli (strain K12)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Catalyzes the oxidation of 3-hydroxypropionaldehyde (3-HPA) to 3-hydroxypropionic acid (3-HP). It acts preferentially with NAD but can also use NADP. 3-HPA appears to be the most suitable substrate for PuuC followed by isovaleraldehyde, propionaldehyde, butyraldehyde, and valeraldehyde. It might play a role in propionate and/or acetic acid metabolisms. Also involved in the breakdown of putrescine through the oxidation of gamma-Glu-gamma-aminobutyraldehyde to gamma-Glu-gamma-aminobutyrate (gamma-Glu-GABA).2 Publications

Catalytic activityi

Gamma-glutamyl-gamma-aminobutyraldehyde + NAD+ + H2O = gamma-glutamyl-gamma-aminobutyrate + NADH.
An aldehyde + NAD(P)+ + H2O = a carboxylate + NAD(P)H.

Enzyme regulationi

Lithium ions exhibits the highest inhibition (97%). To a lesser extent (5-20%), potassium, sodium, and ammonium ions also inhibit PuuC activity. Transition metals, such as copper and zinc ions inhibit PuuC activity by more than 90%. The presence of heavy metals (mercury, silver) or sodium hydrogensulfite in the reaction mixture completely inactivate PuuC; in contrast, disulfide reductants such as DTT and 2-mercaptoethanol significantly increase its activity by 75% and 27%, respectively.1 Publication

pH dependencei

Optimum pH is 8. Activity is highly sensitive to pH variation, and an increase or decrease of one pH unit from the optimal attenuates more than 70% of activity. At pH 6.0, only 6% of the activity remains. At pH.5.0, the activity is completely abolished.1 Publication

Temperature dependencei

Optimum temperature is 37 degrees Celsius. It appears to be stable between 20 and 50 degrees Celsius but becomes very unstable at or above 50 degrees Celsius.1 Publication

Pathwayi: putrescine degradation

This protein is involved in step 3 of the subpathway that synthesizes 4-aminobutanoate from putrescine.
Proteins known to be involved in the 4 steps of the subpathway in this organism are:
  1. Gamma-glutamylputrescine synthetase PuuA (puuA)
  2. Gamma-glutamylputrescine oxidoreductase (puuB)
  3. Aldehyde dehydrogenase PuuC (puuC)
  4. Gamma-glutamyl-gamma-aminobutyrate hydrolase PuuD (puuD)
This subpathway is part of the pathway putrescine degradation, which is itself part of Amine and polyamine degradation.
