Abstract

The genera SPO1-like and Twort-like viruses in the subfamily Spounavirinae of the family Myoviridae have been newly proposed, with the reorganization of the SPO1-related bacteriophages (phages). A criterion defining these viral genera is the presence/absence of DNA modifications. In this study, liquid chromatography/mass spectrometry showed that phages ϕEF24C and K of the subfamily Spounavirinae have unmodified DNA, which classifies them as Twort-like viruses. Moreover, in the subfamily Spounavirinae, DNA modification and elimination of a particular DNA sequence were suggested to be the major antirestriction strategies of the SPO1-like and Twort-like viruses, respectively.
