Analysis of tail spike protein of Pectobacterium bacteriophage PP16 reveals the details of the phage adsorption

Bioinformatic analysis demonstrates the presence of SGNH-domain in the receptor-binding tail spike protein of Pectobacterium bacteriophage PP16. This protein has a modular structure, and the enzymatic part of the tail spike is a subject to horizontal transfer. The experiments with the recombinant protein indicated that the C-part of the tail spike is insufficient for binding with the receptor.
