ABSTRACT:
L-2-oxothiazolidine-4-carboxylate, a sulfur analog of 5-oxoproline, is cleaved by the enzyme 5-oxo-L-prolinase to form cysteine, thus providing the basis for a cysteine delivery system by the addition of L-2-oxothiazolidine-4-carboxylate to base amino acid solutions or by injecting it directly into in vivo cells.
