Recombinant Proteins: A Molecular Tool to Understand Marine Adhesion and to Advance Biomaterials
Advanced Healthcare Materials, Volume 15, Issue 3, 19 January 2026.The production of recombinant proteins represents a fundamental step in the characterisation of marine invertebrate adhesives and in the development of bio‐inspired glues. The association of these proteins with other components such as ions, proteins, polysaccharides, or polymers enables the fabrication of biomaterials for various healthcare ...

, 2006 CP43和CP47是PSII中位于类囊体膜上的两种内周天线色素蛋白复合体，它们都是由六个跨膜的α-螺旋和五个膜外环组成。CP43和CP47的主要功能是把光系统II(PSII)外周天线色素蛋白复合体(LHCII)吸收的能量传给反应中心(RC)，从而引起光化学反应。因此，研究CP43和CP47的结构与功能对于揭示植物光合作用高效吸能、传能的分子机理具有重要意义。由于CP43和CP47的分离纯化比较困难，所以相对于其它的光合膜蛋白来说，人们对CP43和CP47的研究比较少。在本文中，我们在分离 ...
