Relationship between mycobacteriophages L5 and D29 and H. influenzae gene HI1415. Segments of the genomes of the closely related mycobacteriophages L5 and D29 are shown, with genes 6–12 represented as boxes (L5 genes 7–9 and D29 genes 7–9; I and II encode tRNAs as indicated). Below is shown a segment of the H. influenzae genome from within the putative cryptic prophage φflu (shown in full in Fig. 3). Gene 10 of D29 is larger than L5 gene 10 because of an additional 600 bp within the coding region that results in a gene product (gp10) that is 200 amino acids larger than L5 gp10. The upstream parts of gp10 (green) are significantly more similar than the downstream segments (blue), having 81 and 50% amino acid identity, respectively. The “insert” in D29 gene 10 (red) encodes a protein sequence that has 34% identity with the product of H. influenzae HI1415.
