Sano, Konosuke; Yokozeki, Kenzo; Tamura, Fumihide; Yasuda, Naohiko; Noda, Ichiro; Mitsugi, Koji published an article about the compound: 2-Amino-4,5-dihydrothiazole-4-carboxylic acid( cas:2150-55-2,SMILESS:O=C(C1N=C(N)SC1)O ).Computed Properties of C4H6N2O2S. Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:2150-55-2) through the article.
Microorganisms able to form L-cysteine from DL-2-amino-Δ2-thiazoline-4-carboxylic acid (DL-ATC), an intermediate in the chem. synthesis of DL-cysteine, were isolated from soil samples and classified as Pseudomonas AJ3854, Pseudomonas cohaerens, P. desmolytica, and P. ovalis. Thirteen L-cysteine-producing bacteria were also found among 463 stock cultures representing 37 genera. Intact cells of Pseudomonas AJ 3854 produced 6.1 mg of L-cysteine and(or) L-cystine per mL from 10 mg of DL-ATC.3H2O per mL, a molar yield of 100%. This suggests that racemization and asym. hydrolysis occurred simultaneously in this incubation mixture After complete oxidation of cysteine, crystalline cystine was isolated; its configuration was L, based on data from x-ray diffraction, microbioassay, and optical rotation.
