The photosystem of Rhodobacter sphaeroides assembles with zinc bacteriochlorophyll in a bchD (magnesium chelatase) mutant.

Biochemistry - 30 Oct 2007

Jaschke Paul R, Beatty J Thomas

Abstract excerpt

A Rhodobacter sphaeroides bchD (magnesium chelatase) mutant was studied to determine the properties of its photosystem in the absence of bacteriochlorophyll (BChl). Western blots of reaction center H, M, and L (RC H/M/L) proteins from mutant membranes showed levels of 12% RC H, 32% RC L, and 46% RC M relative to those of the wild type. Tricine-SDS-PAGE revealed 52% light-harvesting complex alpha chain and 14%...
