S-Aminoethyl-l-cysteine, also known as thialysine, is a toxic analog of the amino acid lysine in which the second carbon of the amino acid's R-group (side chain) has been replaced with a sulfur atom.
Strictly speaking, L-thialysine is actually considered an S-(2-aminoethyl) analogue of L-cysteine. This compound is known to have cytotoxic affects as it inhibits protein synthesis and lysine 2,3-aminomutase.[1]
