Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 2-Amino-4,5-dihydrothiazole-4-carboxylic acid, is researched, Molecular C4H6N2O2S, CAS is 2150-55-2, about Enzymatic production of L-cysteine from DL-2-amino-Δ2-thiazoline-4-carboxylic acid by Pseudomonas thiazolinophilum: optimal conditions for the enzyme formation and enzymatic reaction.Quality Control of 2-Amino-4,5-dihydrothiazole-4-carboxylic acid.
Cultivation of P. thiazolinophilum AJ 3854 for the production of the enzyme which could form L-cysteine [52-90-4] from DL-2-amino-Δ2-thiazoline-4-carboxylic acid (I) [2150-55-2] and the reaction conditions of this enzyme were investigated. This enzyme was inducible, intracellular, and growth-associated A marked inactivation of enzyme was observed, especially in the growing phase, but could be prevented by 1∼10 mM Mn2+ or by I as inducer at the mid-logarithmic phase. Enzymic degradation of L-cysteine (or L-cystine [56-89-3]) formed from I could be prevented by the addition of hydroxylamine or semicarbazide. Thus, L-cysteine and L-cystine were quant. produced from I. Optimal pH and temperature of enzymic reaction were 8.2 and 42° (2 h), resp. A sigmoidal reaction curve was observed when intact cells were used as enzyme source, but sonic treatment of cells made the curve linear.
