The charged quaternary ammonium compounds – methyl, ethyl and benzylviologens – generate reactive oxygen species in photosynthetic cells. Threeindependent methyl viologen-resistant spontaneous mutants of Synechocys-tis sp. PCC 6803 were identified, in which the conserved R115 residue ofthe Slr1174 protein was replaced with G115, L115 and C115. The Slr1174protein of the DUF990 family is related to the permease subunit of anABC-2-type transporter and its R115 mutation was found to be solelyresponsible for the observed methyl viologen resistance. ...
