In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called 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, published in 1978-12-31, which mentions a compound: 2150-55-2, mainly applied to Pseudomonas enzyme cysteine, Recommanded Product: 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.
After consulting a lot of data, we found that this compound(2150-55-2)Recommanded Product: 2-Amino-4,5-dihydrothiazole-4-carboxylic acid can be used in many types of reactions. And in most cases, this compound has more advantages.
