一般描述

L-Leucine Dehydrogenase is a member of the amino acid dehydrogenase family.

应用

L-Leucine Dehydrogenase from Bacillus cereus has been used to determine the branched-chain amino acids (BCAA) spectrophotometrically in serum samples.

生化/生理作用

Leucine Dehydrogenase is a nicotinamide adenine dinucleotide hydrogen (NADH)-dependent oxidoreductase. It is involved in catalyzing the reductive amination of aliphatic 2-oxo-acids to their respective L-amino acids.

单位定义

One unit will convert 1.0 μmole of L‑leucine to α-ketoisocaproate per min at pH 10.5 at 37 ℃.

其他说明

contains lysine
