Abstract excerpt
The stringent starvation protein A (SspA), an Escherichia coli RNA polymerase (RNAP)-associated protein, has been reported to be essential for lytic growth of bacteriophage P1. Unlike P1 early promoters, P1 late promoters are not recognized by RNAP alone. A phage-encoded early protein, Lpa (late promoter activator protein, formerly called gp10), has been shown to be required for P1 late transcription in vivo....
