Abstrakt: The sequences of two previously defined tail genes, Vand J, of the temperate bacteriophage P2, and those of two new essential tail genes, Wand I, were determined. Their order is the late gene promoter, VWJI, followed by the tail fiber genes H and G, and a transcription terminator. The Vgene product is the small spike at the tip of the tail, and the Jgene product lies at the edge of the baseplate. The Wgene product may be homologous to the product of gene 25 of T4 phage, which is part of the T4 baseplate. A temperature-sensitive mutation in gene Vaffects satellite phage P4 production more than it affects the production of P2 helper phage. P4 mutations that partially compensate for this defect of gene Vlie in the P4 capsid size determination gene, sid.
