Abstract excerpt
cis-acting mutations that affect regulation of the Rhodobacter capsulatus puf operon by oxygen were isolated by placing the mutagenized puf regulatory region 5' to a promoterless Tn5 neo gene, which encodes resistance to kanamycin (Kmr). R. capsulatus mutants that failed to show wild-type repression of KMr by oxygen were selected and analyzed. Four independent clones contained point mutations, three of which were...
