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.

Structural and functional diversity among the aminoacyl-tRNA synthetases prevent infiltration of the genetic code by noncognate amino acids.

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

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
