Molecular architecture of photosynthetic membranes in Rhodobacter sphaeroides: the role of PufX.

The EMBO journal - 25 Feb 2004

Siebert C Alistair, Qian Pu, Fotiadis Dimitrios, Engel Andreas, Hunter C Neil, Bullough Per A

Abstract excerpt

The effects of the PufX polypeptide on membrane architecture were investigated by comparing the composition and structures of photosynthetic membranes from PufX+ and PufX- strains of Rhodobacter sphaeroides. We show that this single polypeptide profoundly affects membrane morphology, leading to highly elongated cells containing extended tubular membranes. Purified tubular membranes contain helical arrays composed...
