General description
L-Leucine Dehydrogenase is a member of the amino acid dehydrogenase family.[1]
Application
L-Leucine Dehydrogenase from Bacillus cereus has been used to determine the branched-chain amino acids (BCAA) spectrophotometrically in serum samples.[2]
Biochem/physiol Actions
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.[3]
Unit Definition
One unit will convert 1.0 μmole of L‑leucine to α-ketoisocaproate per min at pH 10.5 at 37 °C.
Other Notes
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

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

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)

We propose that hyperinsulinemia stimulates protein synthesis when postabsorptive plasma amino acid (AA) concentrations are maintained. During a euglycemic hyperinsulinemic clamp, many AA, notably the branched-chain amino acids (BCAA), decline markedly. Therefore, we tested whether individual plasma AA could be
