The P5 protein from bacteriophage phi
... Our analysis of sequence similarity searches and Cystovirus phage genomes suggests that the P5 protein from bacteriophage phi-6, as the only member of peptidase family U40, is homologous to the lytic transglycosylases and has a lysozyme-like fold. This prediction is consistent with the lytic functio ...
