LYZ and infection: The other ORF (ORF 47 in vRsoP-WF2 and vRsoP-WM2, and ORF 48 in vRsoP-WR2) corresponds to a phage DNA-ejectosome component (Gp16, similar to that of phage T7), essential for phage morphogenesis and infection [66], a peptidoglycan lytic exotransglycosylase with a lysozyme-like domain (IPRO23346) found in glycosyl hydrolases and transglycosylases.
