De-etiolation-induced protein 1 (DEIP1) mediates assembly of the cytochrome b 6 f complex in Arabidopsis

Abstract

The Cytb6f complex is a multi-subunit enzyme that couples the two photosystems during the light reactions of photosynthesis. Here the authors show that the thylakoid-localized DEIP1 protein interacts with the PetA and PetB subunits, and is essential for Cytb6f complex assembly in Arabidopsis.
