Sequence analysis of the Lactobacillus temperate phage Sha1.

Bacteriophage Sha1, a newly isolated temperate phage from a mitomycin-C-induced lysate of Lactobacillus plantarum isolated from Kimchi, has an isometric head (58 nm × 60 nm) and a long tail (259 nm × 11 nm). The double-strand DNA genome of the phage Sha1 was 41,726 base pairs (bp) long, with a G+C content of 40.61%. Bioinformatic analysis of Sha1 shows that this phage contains 58 putative open reading frames (ORFs). Sha1 can be classified as a member of the large family Siphoviridae by genomic structure and morphology. To our knowledge, this is the first report of genomic sequencing and characterization of temperate phage Sha1 from wild-type L. plantarum isolated from kimchi in Korea.
