Protein

Aldehyde dehydrogenase B

Gene

aldB

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

Functioni

Catalyzes the NADP-dependent oxidation of diverse aldehydes such as chloroacetaldehyde, acetaldehyde, propionaldehyde, benzaldehyde, mafosfamide, 4-hydroperoxycyclophosphamide. Its preferred substrates are acetaldehyde and chloroacetaldehyde.

Cofactori

Enzyme regulationi

Negatively regulated by fis. Positively regulated by RpoS and crp. Induced by ethanol. Expression is maximally induced during the transition from exponential phase to stationary phase.

Kineticsi

the highest catalytic efficiency was observed with acetaldehyde.

  1. KM=2.5 µM for acetaldehyde
  2. KM=3.6 µM for chloroacetaldehyde
  3. KM=5.8 µM for propionaldehyde
  4. KM=56.8 µM for benzaldehyde
  5. KM=900 µM for 4-hydroperoxycyclophosphamide
  1. Vmax=2 µmol/min/mg enzyme with acetaldehyde as substrate
  2. Vmax=3.3 µmol/min/mg enzyme with chloroacetaldehyde as substrate
  3. Vmax=1 µmol/min/mg enzyme with propionaldehyde as substrate
  4. Vmax=0.6 µmol/min/mg enzyme with benzaldehyde as substrate
  5. Vmax=0.2 µmol/min/mg enzyme with 4-hydroperoxycyclophosphamide
