摘要:三种阿魏酸酯酶 Ec 3.1.1.73 (Fae),即来自黑曲霉的 Fae A (Anfaea),来自构巢曲霉的 Fae C (Andfaec) 以及来自特异腐质霉 (Ultraflo L) 的商业 β-葡聚糖酶混合物中的 Fae 活性测试了它们在四种离子液体(il)系统中催化芥子酸与甘油酯化的能力. Il 系统系统地由两对选定的阳离子和阴离子组成,分别为:[bmim][pf6],[c2Ohmim][pf6],[bmim][bf4] 和 [c2Ohmim][bf4]. Anfaea 在基于 [pf6] 的 Il 中具有活性,而 Ultraflo L 中的 Andfaec 和 Fae 没有明显的活性,并且在 Il 系统中通常不稳定. Il 系统中的 Fae 稳定性显然高度依赖于酶结构,值得注意的是 Anfaea 与 Il 相容性脂肪酶的相似性可以解释其稳定性. Anfaea 在缓冲液中的热稳定性高于 Il 系统,但在 40 oc 及以下,缓冲液和基于 [pf6]− 的系统之间 Anfaea 的稳定性没有显着差异:Anfaea置于[bmim] 中稳定][pf6] 和 [c2Ohmim][pf6] 系统在 40 oc 下反应 2 小时.然而,Il 阴离子对稳定性有重大影响:[bf4]− 导致 Anfaea 快速失活,而 [pf6]− 则不然.阳离子没有类似的效果.这些观察结果可以通过 Cosmo-Rs 模拟用 Il 阳离子和阴离子的氢键能力来解释.

摘要:The invention relates to an efficient method for synthesizing self-assembling artificial proteins (SAPs) utilizing a catalytic host-guest system. The process involves encapsulating hydrophobic probes with cyclodextrin, performing site-specific protein bioconjugation, and employing a second catalysis cycle for enhanced labeling. SAPs produced through this method are versatile and find applications in therapeutic delivery and diagnostics. The process is simplified, scalable, cost-effective, and environmentally sustainable, addressing the challenges of traditional SAP synthesis. By offering improved yield, functionality, and structural integrity, this invention advances the potential of SAPs in medical and industrial fields.
