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.

Thermus thermophilus exhibits hypersensitivity to a lysine analog, (S)-2-aminoethyl-cysteine (AEC). Cosmid libraries were constructed using genomes from two AEC-resistant mutants, AT10 and AT14, and the cosmids that conferred AEC resistance on the wild-type strain were isolated. When the cosmid library

Aspartate kinase (AK) catalyzes the first step of the biosynthesis of the aspartic acid family amino acids, and is regulated via feedback inhibition by end-products including Thr and Lys. To elucidate the mechanism of this inhibition, we determined the crystal

Structural and functional diversity among the aminoacyl-tRNA synthetases prevent infiltration of the genetic code by noncognate amino acids. To explore whether these same features distinguish the synthetases as potential sources of resistance against antibiotic amino acid analogues, we investigated bacterial

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

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
