    摘要:
    一种制备硬脂酸锌颗粒水分散体的方法,包括以下步骤:形成至少一种表面活性剂和水的混合物,将混合物加热至约40℃到低于硬脂酸锌的熔点温度,加入含金属的硬脂酸盐于搅拌下混合物中,向混合物中加入水溶性的锌盐溶液,使得硬脂酸盐和锌盐在混合物中反应形成硬脂酸锌颗粒,完成加入锌盐溶液或加入硬脂酸盐后继续加热和搅拌以继续反应,最后冷却以获得硬脂酸锌颗粒水分散体。该方法形成了一种稳定的纳米级硬脂酸锌颗粒水分散体,特别适用于涂覆调色剂颗粒。

  • Characterization of LipN (Rv2970c) of<i>Mycobacterium Tuberculosis</i>H37Rv and its Probable Role in Xenobiotic Degradation
    作者:Dipendrasinh Jadeja、Nandita Dogra、Stuti Arya、Gurpreet Singh、Gurdyal Singh、Jagdeep Kaur
    DOI:10.1002/jcb.25285
    日期:2016.2
    RHC-80267 and N-bromosuccinimide inhibited LipN enzyme activity completely. Interestingly, Trp145, a non active-site residue, demonstrated functional role to retain enzyme activity. The enzyme was localized in cytosolic fraction of M. tuberculosis H37Rv. The enzyme was able to synthesize ester of butyric acid, methyl butyrate, in presence of methanol. LipN was able to hydrolyze 4-hydroxyphenylacetate
    LipN(Rv2970c)属于结核分枝杆菌H37Rv的Lip家族,与人激素敏感性脂肪酶同源。该酶表现出对短碳链底物的偏爱,该底物在45℃/ pH 8.0下具有最佳活性,在pH 6.0至9.0之间具有稳定性。该酶的比活为217 U / mg蛋白,pNP丁酸酯为底物。将三丁酸甘油酯水解为二丁酸和一丁酸。确认该酶的活性位点残基为Ser216,Asp316和His346。Tetrahydrolipstatin,RHC-80267和N-溴代琥珀酰亚胺可完全抑制LipN酶的活性。有趣的是,非活性位点残基Trp145表现出保留酶活性的功能。该酶位于结核分枝杆菌H37Rv的胞质级分中。该酶能够合成丁酸的酯,丁酸甲酯,在甲醇存在下。LipN能够将4-羟基苯乙酸酯水解为对苯二酚。该基因在体外生长条件下不表达,而在结核分枝杆菌H37Ra巨噬细胞感染后6小时观察到了rv2970c基因的表达。在个别体外应激条件下,
