Project Description

The project will provide molecular and mechanistic insight into coordinated modular assembly of photosystems including the structural and photoprotective role of several assembly factors. Apart from high resolution structures of several small PSI and PSII assembly intermediates and large PSII/PSI supercomplexes the project will utilize a unique cryo-electron tomography approach to localize and characterize the PSI/PSII biogenesis in situ in the cyanobacterial cell. The project is separated into three main objectives:

•      Objective 1: Preparation of assembly intermediates in sufficient quality and quantity for cryo-EM structural studies
•      Objective 2: Structural analysis of the intermediates at near atomic resolution
•      Objective 3: Exploring the localization of assembly intermediates in situ by cryo-section-ET
