Cyclophilin anaCyp40 regulates photosystem assembly and phycobilisome association in a cyanobacterium

Abstract

Cyclophilins are proteins found in many organisms, where they can play roles as chaperones, in signal transduction, or other functions. Here, Yadav et al. show that a cyanobacterial cyclophilin is involved in stress responses and in assembly of photosynthetic complexes, and displays unique structural features.
