Two strategies of using the sequence of bacteriophage A500 recombination site (AttP) to find potential cases of HGT. a The structure of rusticalin-like gene of ascidian Ciona intestinalis. Exons are shown as boxes. b AttP nucleotide sequence of bacteriophage A500 used as a query for BBLASTn search. c Cysteine-rich repeats of the rusticalin and rusticalin-like proteins, used for jackhmmer search
