FIG 3.

Organization of sequences in the host-ΦLM21 prophage junctions. The sequences present in the phage DNA are shown in capital letters. A 55-bp region of identity shared by the phage and the lysogen is shown in italic letters. (A) Schematic representation of the prophage ΦLM21 integration site in Sinorhizobium sp. LM21. Only ORFs proximal to the junction, encoding integrase (Orf1) and ligase (Orf73), are depicted; the tRNA(Pro) sequence is underlined. (B) Structure of tRNA(Pro), with an arrow indicating the 5′ position of the common core. (C) Sequence alignments of attL and attR. The tRNA(Pro) sequence is marked with an arrow.
