Abstract excerpt
We characterized the function of the -35 hexamer in the promoter and an element just upstream, UPE, in the expression in a unicellular cyanobacterium, Microcystis aeruginosa K-81, of the light-responsive gene psbA2, which encodes a reaction center key protein for photosynthesis. A series of mutants with mutations at the -35 hexamer (-35 to -30) and a novel conserved upstream element (UPE: -45 to -36, +1 referring...
