Abstract A simple colorimetric assay for measuring leucine-α-ketoglutarate transamination is described. It is reproducible, sensitive, and specific for α-ketoisocaproate. α-Ketoglutarate interferes only in that high concentrations decrease the color yield.

Hypoglycæmic Response to Leucine in a Leucine-sensitive Man [PDF]
IT has been reported previously1,2 that certain individuals show a profound lowering of the blood glucose-level following ingestion of leucine or iso-valeric acid and that this is a familial trait.

Leucine degradation in sheep [PDF]
1. In vitro leucine catabolism in adipose tissue, skeletal muscle, kidney and liver homogenates was studied in sheep.2. In Expt 1, Suffolk × Targhee ram lambs were slaughtered at 1, 28, 56, 84, 112, 140, 168, 196, 224 and 365 d of age. In Expt 2, 5-month-old crossbred wethers were fed on 80, 120 or 180 g crude protein (nitrogen × 6·25) /kg diets for 4 ...

Leucine in the Sky with Diamonds [PDF]
AbstractNew structures of LD motifs bound to the focal adhesion targeting domain show that the motifs are recognized as amphipathic α helices. The structures highlight the structural and functional diversity of leucine and aspartic acid-based targeting motifs.

Leucine 2,3-aminomutase, an enzyme of leucine catabolism.
The initial step in the fermentation of leucine to acetate, isobutyrate, and ammonia by Clostridium sporogenes is the B12 coenzyme-dependent conversion of alpha-leucine to beta-leucine (3-amino-4-methylpentanoate). The amino group migration reaction, catalyzed by leucine 2,3-aminomutase, is reversible and is inhibited by intrinsic factor.

Mitochondrial leucine tRNA level and PTCD1 are regulated in response to leucine starvation [PDF]
Pentatricopeptide repeat domain protein 1 (PTCD1) is a novel human protein that was recently shown to decrease the levels of mitochondrial leucine tRNAs. The physiological role of this regulation, however, remains unclear. Here we show that amino acid starvation by leucine deprivation significantly increased the mRNA steady-state levels of PTCD1 in ...

A Heterospecific Leucine Zipper Tetramer
Protein-protein interactions play an essential role in the assembly of the macromolecular complexes that form functional networks and control cellular behavior. Elucidating principles of molecular recognition governing potentially complex interfaces is a challenging goal for structural and systems biology.

Leucine Aminopeptidase in Candida Albicans
Since the late 19th century, there have been numerous publications on proteolytic enzymes in dermatophytes (for literature see 1-5). Bodin (1907), Mallinckrodt-Haupt (1928), and Tate (1929) stated that active proteolytic enzymes (e.g. trypsin, casease, renin, gelatinase (1, 2), or enzymes with activity very similar to trypsin (3)) are present in the ...
