Alanyl dipeptides such as ala-leu, ala-lys, ala-gly, ala-pro, ala-tyr and ala-phe may be used in physicochemical studies or to evaluate dipeptide separation technologies. Alanyl dipeptides may also be used for studying cell uptake mechanisms, dipeptide metabolism or cell growth supplementation benefits.

BacD is an ATP-dependent dipeptide ligase responsible for the biosynthesis of L-alanyl-L-anticapsin, a precursor of an antibiotic produced by Bacillus spp. In contrast to the well-studied and phylogenetically related D-alanine: D-alanine ligase (Ddl), BacD synthesizes dipeptides using L-amino acids as

Myocardial ischemia and other acute coronary syndromes are leading causes of death worldwide, and often result from a thrombus that blocks an atherosclerotic coronary artery. A key enzyme in thrombus formation is the serine protease thrombin, which is responsible for
A ligand-exchange capillary electrophoresis was explored, with L-ornithine as the ligand and copper(II) as the central ion. Its applicability was demonstrated with underivatized and dansyl amino acids, a dipeptide, and drugs with amino alcohol structure. The enantioselectivity was found to

A replicate heart-cut column-switching HPLC method combined with two switching valves was newly developed for the simultaneous determination of three antihypertensive peptides (Ala-Phe, Tyr-Pro, and Trp-Tyr) in tryptic casein hydrolysate in one run-in assay. After a first separation on an

In this study we describe, the construction of a co-expression vector allowing simultaneous production of Thermoplasma volcanium 20S proteasome alpha- and beta-subunits in Escherichia coli. This heterologous expression system provided high level production of fully active 20S proteasome that can
