Regulation of transcription in the segment of the bacteriophage T4 genome containing three of the head protein genes: plasmid-specific and phage chromosome-specific effects.
The activity of the phage T4 late promoters, P22, P23, and P24, is regulated by the gene 33, 45, and 55 products and, through the gene 43 product, by DNA replication. The accumulation of RNA of opposing polarity, with 5' ends mapping to Q22 and Q23, as described by T. Elliott, G. A. Kassavetis, and E. P. Geiduschek (Virology, 1984, 260-282), is subject to the same regulation. When located on a plasmid, the P23 promoter escapes the gene 43 product dependence.
