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.

Catalytic activityi

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

Kineticsi

  1. KM=2.1 mM for L-leucine
  2. KM=3.3 mM for L-isoleucine
  3. KM=12.5 mM for L-valine
  4. KM=0.31 mM for NAD+
  5. KM=1.0 mM for 4-methyl-2-oxopentanoate
  6. KM=3.8 mM for 2-oxoisovalerate
  7. KM=2.4 mM for 2-oxovalerate
  8. KM=0.25 mM for NADH
  9. KM=330 mM for NH3

pH dependencei

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

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.
