Modulation of lambda plasmid and phage DNA replication by Escherichia coli SeqA protein.

Abstract excerpt

SeqA protein, a main negative regulator of the replication initiation of the Escherichia coli chromosome, also has several other functions which are still poorly understood. It was demonstrated previously that in seqA mutants the copy number of another replicon, the lambda plasmid, is decreased, and that the activity of the lambda p(R) promoter (whose function is required for stimulation of ori lambda) is lower...
