Amino acid substitutions in the D1 protein of photosystem II affect QB- stabilization and accelerate turnover of D1.

Zeitschrift fur Naturforschung. C, Journal of biosciences - 1 May 1990

Abstract excerpt

Isogenic strains of Synechococcus PCC7942 were genetically engineered so that copy I of the gene psb A was mutated at specific sites. These mutations resulted in replacements of Ser 264 by Gly or Ala and of Phe 255 by Tyr or Leu in the D1 protein. The mutants were resistant to herbicides inhibiting electron transfer in photosystem II. All mutants exhibited alterations in the stability of QB- as demonstrated by a...
