S-(2-Aminoethyl)-L-cysteine (AEC) hydrochloride is used as a lysine analogue for comparative analysis with other lysine analogues. S-(2-Aminoethyl)-L-cysteine is an alternative substrate useful for characterizing lysine cyclodeaminase from Streptomyces pristinaespiralis. AEC may be used as a non-antibiotic selection agent for genetically engineered soybeans expressing a lysine insensitive DHPS gene. AEC is being studied as an amino acid antibiotic.

The expression of cyclotides-macrocyclic plant peptides-was profiled in six violets, Viola cotyledon, V. biflora, V. arvensis, V. tricolor, V. riviniana, and V. odorata, by LC-MS. All were found to express notably complex mixtures, with single species containing >50 cyclotides. To

In Thermus thermophilus homocitrate synthase (HCS) catalyzes the initial reaction of lysine biosynthesis through alpha-aminoadipic acid, synthesis of homocitrate from 2-oxoglutarate and acetyl-CoA. HCS is strongly inhibited by lysine, indicating that the biosynthesis is regulated by the endproduct at the

We first report the mechanism for the inhibitory effect of the lysine analog, thialysine on human acute leukemia Jurkat T cells. When Jurkat T cells were treated with thialysine (0.32-2.5 mM), apoptotic cell death along with several biochemical events such

To enhance L-lysine secretion in Lactobacillus plantarum. An S-2-aminoethyl-L-cystein (AEC)-resistant mutant of L. plantarum was isolated, and it produced L-lysine at considerably higher level than the parent strain. Aspartokinase in the mutant has been desensitized to feedback inhibition by L-lysine.

In Phenylketonuria (PKU), the peptide structure of the protein substitute (PS), casein glycomacropeptide (CGMP), is supplemented with amino acids (CGMP-AA). CGMP may slow the rate of amino acid (AA) absorption compared with traditional phenylalanine-free amino acids (Phe-free AA), which may
