Nonessential region of bacteriophage P4: DNA sequence, transcription, gene products, and functions.

Journal of virology - 1 Jan 1990

Abstract excerpt

We sequenced the leftmost 2,640 base pairs of bacteriophage P4 DNA, thus completing the sequence of the 11,627-base-pair P4 genome. The newly sequenced region encodes three nonessential genes, which are called gop, beta, and cII (in order, from left to right). The gop gene product kills Escherichia coli when the beta protein is absent; the gop and beta genes are transcribed rightward from the same promoter. The...
