Structure of all known lactococcal
prophage genomes. Genome extremities correspond to attB sites.
ORFs are shown as arrows, oriented in the direction of their transcription,
with designation below. Arrows with identical colour indicate proteins
with >70% sequence identity (plain colour), or
20–70% sequence identity (hatched colour). Colour
rectangles in the background indicate DNA regions with >60% sequence
identity. A white box indicates IS983. Sequences
are taken from van Sinderen et al. (5) (r1t), G.Fitzgerald
and D.van Sinderen (personal communication; Tuc2009) and this study
(bIL285, bIL286, bIL309, bIL310, bIL311 and bIL312).
