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 °C.
其他说明
contains lysine

Unnatural amino acids (UAAs) play a key role in modern medicinal chemistry such as small molecules and peptide-based drugs with fast-growing markets. Low efficiency for natural enzymes including leucine dehydrogenase (LeuDH, EC1.4.1.9) are one major challenge for UAA production. Here

X-ray crystallographic studies revealed that various amino acid dehydrogenases fold into two domains in each subunit, a substrate-binding domain and an NAD(P)(+)-binding domain (Baker, P. J., Turnbull, A. P., Sedelnikova, S. E., Stillman, T. J., and Rice, D. W. (1995)

Previous studies of the biosynthetic enzymes involved in the assembly of scytonemin (1), a cyanobacterial sunscreen, have identified beta-ketoacid 2 as an important intermediate that is produced by ThDP-dependent enzyme ScyA. We now report that ScyC, previously annotated as a

A liquid chromatographic system with a co-immobilized leucine dehydrogenase-NADH oxidase reactor is described for the determination of branched-chain amino acids such as I-leucine, I-isoleucine and I-valine. The enzymes were simultaneously immobilized on tresylate-containing poly(vinyl alcohol) beads. The separation was achieved

The L-leucine dehydrogenase gene from Bacillus cereus (DSM 626) was cloned from a partial genomic library and sequenced. The open reading frame has 1101 bp and codes for a protein of 39.9 kDa. The deduced amino acid sequence of the
