Fe~(3+)调节下的桑蚕丝素蛋白β-sheet结构对碳酸钙晶型的控制 

碳酸钙(CaCO3)是自然界存在最广泛的无机矿物之一,生物体能通过有机质的预组装来实现对其晶型的控制。本文主要通过加入不同浓度的Fe3+对溶液中丝素蛋白构象进行调控实现CaCO3的可控结晶。我们采用的是CO2扩散法,即在结晶体系中加入丝

用于膜蛋白研究的新型β-sheet多肽去垢剂 

膜蛋白具有重要的生理功能,包括物质传递、能量转换和信号传导等。膜蛋白的研究对于生物医药领域的发展起着至关重要的作用,在FDA批准的上市药物中,目前约有一半以膜蛋白作为靶点。但是,限于研究手段,膜蛋白研究还很困难,远远落后于水溶性蛋白。膜蛋白的疏水性决定了其必须依靠合适的去垢剂才能稳定地存在于水溶液中。我们设计了一...
