General description
Native L-leucine dehydrogenase from Bacillus cereus. Catalyzes the NAD+-dependent conversion of L-leucine to α-ketoisocaproate. Suitable for the production of L-tertiary leucine amino acids.
Native L-leucine dehydrogenase from Bacillus cereus. Purified enzyme that catalyzes the NAD-dependent conversion of L-leucine to α-ketoisocaproate. Suitable for the production of L-tertiary leucine amino acids. Has an optimal pH of 10.5-10.8 for L-leucine substrate and 9.4 for α-ketoisocaproate substrate. Has an optimal temperature of 65°C.
pH optimum 10.5-10.8 (L-leucine substrate) and 9.4 (α-ketoisocaproate substrate), temperature optimum 65°C.
Warning
Toxicity: Standard Handling (A)
Unit Definition
