将烯酰硫酯还原酶的进化起源多样性与立体特异性联系起来:测定和解释由来自 Streptomyces collinus 的巴豆酰 CoA 还原酶催化的新型立体化学反应过程
摘要:
使用放射化学测定法确定了 Streptomyces collinus 的新型巴豆酰 CoA 还原酶 (CCR) 还原巴豆酰 CoA 的立体化学过程。显示该反应随着氢从 NADPH 的 pro-4S 位置转移到巴豆酰 CoA 的 β-碳的 Re 面而进行。这种转移代表了烯酰硫酯还原酶催化 NADPH 的 pro-4S 氢转移到基材的 Si 面的第一个例外。在 CCR 催化的反应中,在 α-碳的 Re 面上添加溶剂氢的观察表明,巴豆酰 CoA 的整体还原以反方式进行。CCR 催化的反应的整体立体化学结果不同于之前观察到的烯酰硫酯还原酶的四种立体化学结果。重要的是,CCR 的预测氨基酸序列也已显示与其他烯酰硫酯还原酶无关。基于...

The present invention relates to substituted benzophenones of structural Formula I employed as small molecule inhibitor for controlling obesity. The present invention further relates to screening of small molecule inhibitors against p300 which selectively targets histone butyrylation thereby specifically inhibiting adipogenesis further aiding to prevention of weight gain. The present invention reveals that histone butyrylation increases during adipogenesis. Hence, inhibition of histone butyrylation by a small molecule inhibitor would be a promising therapeutic strategy to control obesity. Significantly, besides inhibiting adipogenesis in cellular model, it also prevents weight gain in high fat diet based mouse model system, indicating the possible use of the scaffold for obesity control.

The stereochemicalcourse of reduction of crotonyl CoA by the novel crotonyl CoA reductase (CCR) of Streptomyces collinus was determined using a radiochemical assay. The reaction was shown to proceed with transfer of the hydrogen from the pro-4S position of NADPH to the Re face of the β-carbon of crotonyl CoA. This transfer represents the first exception to the observation that enoyl thioester reductases
