So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Sano, Konosuke; Yokozeki, Kenzo; Tamura, Fumihide; Yasuda, Naohiko; Noda, Ichiro; Mitsugi, Koji researched the compound: 2-Amino-4,5-dihydrothiazole-4-carboxylic acid( cas:2150-55-2 ).Category: pyrazines.They published the article 《Microbial conversion of DL-2-amino-Δ-thiazoline-4-carboxylic acid to L-cysteine and L-cystine: screening of microorganisms and identification of products》 about this compound( cas:2150-55-2 ) in Applied and Environmental Microbiology. Keywords: cysteine aminothiazolinecarboxylate bacteria; Pseudomonas aminothiazolinecarboxylate hydrolysis; stereochem hydrolysis cysteine production Pseudomonas. We’ll tell you more about this compound (cas:2150-55-2).
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.
