Lactobacillus casei Zhang has one defective prophage integrated into its chromosome, designated as Lcazh1. The 12.5‐kb long nucleotide sequence contains 20 coding regions, 11 of which can be assigned functions by homologue searching and domain characterisation. With the exception of one uncharacterised protein cluster, genes encoded by Lcazh1 shared extensive similarities and strong synteny with the prophage Lp3 found in the chromosome of Lactobacillus plantarum WCSF1. It is the first time that prophages from different species of Lactobacillus were observed sharing clear similarities, implicating the possibility of lateral DNA transfer.
