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.Ryu, Ok Hee; Oh, Sea Wha; Yoo, Seung Ku; Shin, Chul Soo researched the compound: 2-Amino-4,5-dihydrothiazole-4-carboxylic acid( cas:2150-55-2 ).Recommanded Product: 2-Amino-4,5-dihydrothiazole-4-carboxylic acid.They published the article 《The stability of L-ATC hydrolase participating in L-cysteine production》 about this compound( cas:2150-55-2 ) in Biotechnology Letters. Keywords: aminothiazolinecarboxylate hydrolase stabilization cysteine manufacture. We’ll tell you more about this compound (cas:2150-55-2).
In the production of L-cysteine from DL-2-amino-Δ2-thiazoline-4-carboxylic acid (DL-ATC), the stability of the relevant enzymes produced by Pseudomonas sp. was tested, and strategies to improve the stability of L-ATC hydrolase were investigated with respect to water activity and ionic strength. Among the 3 enzymes which participate in L-cysteine production, i.e., ATC racemase, L-ATC hydrolase, and S-carbamyl-L-cysteine hydrolase, L-ATC hydrolase is the least stable. Various mixtures of salts and sorbitol were added to adjust the water activities of the tested solutions As the water activity decreased from 0.93 to 0.80, the stability of L-ATC hydrolase was sharply enhanced. In the absence of sorbitol, the stability of L-ATC hydrolase increased in proportion to ionic strength. Even though enzyme stability was not good at a low ionic strength, it was enhanced by lowering the water activity with the addition of sorbitol. The half-life of L-ATC hydrolase in sorbitol-salt mixtures increased by 10- to 20-fold compared to that of a control.
