Abstract

Read online

Rhodobacter (Rba.) sphaeroides is a model organism for studying bacterial photosynthesis. Here, the authors present the 2.9 Å cryo-EM structure of the monomeric light-harvesting-reaction center core complex from Rba. sphaeroides strain IL106, which revealed the position and conformation of PufX and the presence of an additional component protein-U, an integral membrane protein.
