Functional Update of the Auxiliary Proteins PsbW, PsbY, HCF136, PsbN, TerC and ALB3 in Maintenance and Assembly of PSII

摘要: Assembly of Photosystem (PS) II in plants has turned out to be a highly complex process which, at least part, occurs sequential order and requires many more auxiliary proteins than subunits present the complex. Owing high evolutionary conservation subunit composition three-dimensional structure PSII complex, most plant factors involved biogenesis originated from cyanobacteria only rarely evolved de novo. Furthermore, chloroplasts initial assembly steps occur non-appressed stroma lamellae, whereas final including attachment major LHCII antenna takes place grana regions. The lamellae are also where part repair occurs, which very likely involves factors. In thylakoid membrane, so-called centers, contact with plasma membrane. Here, we provide an update on structures, localisations, topologies, functions, expression interactions low molecular mass PsbY, PsbW HCF136, PsbN, TerC ALB3, assisting protein insertion into
