LIPIDIC CUBIC PHASE GROWN REACTION CENTRE FROM RHODOBACTER SPHAEROIDES, EXCITED STATE
Overview
In bright light the photosynthetic reaction center (RC) of Rhodobacter, sphaeroides stabilizes the P(+)(870).Q(-)(A) charge-separated state and, thereby minimizes the potentially harmful effects of light saturation., Using X-ray diffraction we report a conformational change that occurs, within the cytoplasmic domain of this RC in response to prolonged, illumination with bright light. Our observations suggest a novel, structural mechanism for the regulation of electron transfer reactions in, photosynthesis.
About this Structure
2BNS is a Protein complex structure of sequences from Rhodobacter sphaeroides with FE2, PO4, CL, BCL, BH1, MST and U10 as ligands. Known structural/functional Site: AC1. Full crystallographic information is available from OCA.
