Altered (copy-up) forms of initiator protein pi suppress the point mutations inactivating the gamma origin of plasmid R6K.

The R6K gamma origin core contains the P2 promoter, whose -10 and -35 hexamers overlap two of the seven binding sites for the R6K-encoded pi protein. Two mutations, P2-201 and P2-203, which lie within the -35 region of P2, are shown to confer a promoter-down phenotype. We demonstrate here that these...
