Genome organization of membrane-containing bacteriophage PRD1

We have determined the nucleotide sequence of the late region (11 kbp) of the lipid-containing bacteriophage PRD1. Gene localization was carried out by complementing nonsense phage mutants with genomic clones containing specific reading frames. The localization was confirmed by sequencing the N-termini of isolated gene products as well as sequencing the N-termini of tryptic fragments of the phage membrane-associated proteins. This, with the previously obtained sequence of the early regions, allowed us to organize most of the phage genes in the phage genome.
