Genetic map of phage rV5 with each line representing 21 kb of the sequence. Genes in colour represent those whose products exhibit homologs in the NCBI nonredundant databases, while those illustrated in black lack homologs. Green, brown and grey colored genes specify proteins involved in morphogenesis, DNA metabolism and lysis, respectively. The grey box labeled “non-coding” contained no ORFs. Promoters are illustrated as pink arrowheads, while rho-independent terminators are displayed as stem-loop structure, also in pink.
