Tandem sequence duplications functionally complement deletions in the D1 protein of photosystem II.

The Journal of biological chemistry - 14 Jul 1995

Kless H, Vermaas W

Abstract excerpt

Obligate photoheterotrophic mutants of the cyanobacterium Synechocystis sp. PCC 6803 that carry deletions of conserved residues in the plastoquinone-binding niche of the D1 protein were used to select for spontaneous mutations that restore photoautotrophic growth. Spontaneous pseudorevertants emerged from two deletion mutants, delta YNIV246-9 and delta NN266-7, when the cultures were maintained long after the...
