Crystal structure of RC-LH1 core complex from Rhodopseudomonas palustris
Overview
The crystal structure at 4.8 angstrom resolution of the reaction, center-light harvesting 1 (RC-LH1) core complex from Rhodopseudomonas, palustris shows the reaction center surrounded by an oval LH1 complex that, consists of 15 pairs of transmembrane helical alpha- and beta-apoproteins, and their coordinated bacteriochlorophylls. Complete closure of the RC by, the LH1 is prevented by a single transmembrane helix, out of register with, the array of inner LH1 alpha-apoproteins. This break, located next to the, binding site in the reaction center for the secondary electron acceptor, ubiquinone (UQB), may provide a portal through which UQB can transfer, electrons to cytochrome b/c1.
