Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Journal of Microbiology and Biotechnology called Analysis of the reaction steps in the bioconversion of D,L-ATC to L-cysteine, Author is Ryu, Ok Hee; Shin, Chul Soo, which mentions a compound: 2150-55-2, SMILESS is O=C(C1N=C(N)SC1)O, Molecular C4H6N2O2S, Electric Literature of C4H6N2O2S.
The reaction steps involved in the bioconversion of a chem. synthesized precursor, D,L-2-amino-Δ2-thiazoline-4-carboxylic acid (D,L-ATC), to L-cysteine and the properties of the involved enzymes were investigated. It was found that the conversion consisted of two steps, i.e., D,L-ATC to S-carbamyl-L-cysteine (S-C-L-cysteine) and S-C-L-cysteine to L-cysteine, and the S-C-L-cysteine was an intermediate between them. While the enzymes involved in the reactions were induced by the addition of D,L-ATC as an inducer, S-C-L-cysteine induced only the enzyme involved in the latter step. The conversion of S-C-L-cysteine to L-cysteine could be also carried out in the presence of hydroxylamine and its rate was much faster than that by the corresponding enzyme. On the other hand, L-cysteine (or L-cystine) was decomposed to evolve H2S by the enzyme considered to be a kind of desulfhydrase. However, hydroxylamine was a perfect inhibitor for this enzyme.
