Azioni biochim/fisiol

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.

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

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.
