Biochem/physiol Actions

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.

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

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

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.

Beta-lactamases and penicillin-binding proteins are bacterial enzymes involved in antibiotic resistance to beta-lactam antibiotics and biosynthetic assembly of cell wall, respectively. Members of these large families of enzymes all experience acylation by their respective substrates at an active site serine

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
