FIG. 5.

Comparison of P. freudenreichii phage B5 proteins (Orf5, Orf4, Orf3, Orf7, Orf6) (this study) and structural proteins of E. coli phage fd (pVIII, pVII, pIX, pVI, pIII) (2). Charged residues are indicated by red (positive charge) or blue (negative charge) boxes. Hydrophobic helices and leader peptide sequences are indicated by green and yellow rectangles, respectively. Repeats are indicated by arrowheads. Transmembrane helices of phage B5 proteins have been predicted by using the PHD program (28).
