Many combinations of amino acid sequences in a conserved region of the D1 protein satisfy photosystem II function.

Journal of molecular biology - 10 Feb 1995

Kless H, Vermaas W

Abstract excerpt

The putative de helix of the D1 protein is located at the acceptor side of photosystem II (PS II) and serves as an indispensable part of a niche that binds the secondary plastoquinone QB. Combinatorial mutagenesis was applied to a stretch of four residues in a highly conserved region of this putative helix in order to reveal amino acid combinations that are able to support PS II function. An obligate...
