Protein

Leucine dehydrogenase

Gene

ldh

Organism
Bacillus licheniformis
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at protein leveli

Functioni

Catalyzes the reversible deamination of L-leucine to 4-methyl-2-oxopentanoate. Can also use other substrates such as L-isoleucine, L-valine and L-2-aminobutyrate. The 2-oxo analogs of branched-chain and straight-chain amino acids serve as good substrates for the reverse reaction.1 Publication

Catalytic activityi

L-leucine + H2O + NAD+ = 4-methyl-2-oxopentanoate + NH3 + NADH.1 Publication

Kineticsi

  1. KM=2.1 mM for L-leucine1 Publication
  2. KM=3.3 mM for L-isoleucine1 Publication
  3. KM=12.5 mM for L-valine1 Publication
  4. KM=0.31 mM for NAD+1 Publication
  5. KM=1.0 mM for 4-methyl-2-oxopentanoate1 Publication
  6. KM=3.8 mM for 2-oxoisovalerate1 Publication
  7. KM=2.4 mM for 2-oxovalerate1 Publication
  8. KM=0.25 mM for NADH1 Publication
  9. KM=330 mM for NH31 Publication

pH dependencei

Optimum pH is 10.3 for the oxidative deamination of L-leucine.1 Publication

Temperature dependencei

Thermostable. Retains full activity on heating at 65 degrees Celsius for 1 hour, but loses the activity completely on heating at 70 degrees Celsius for 1 hour.1 Publication
