Viruses encode tRNA and anti-retron to evade bacterial immunity

A. H. Azam, K. Chihara, K. Kondo, T. Nakamura, S. Ojima, A. Tamura, W. Yamashita, L. Cui, Y. Takahashi, K. Watashi, K. Kiga

This study identifies two viral strategies to evade bacterial retrons: supplying tRNATyr to counteract retron 78 and using Rad to degrade retron noncoding RNA precursors.

Analysis host-recognition mechanism of staphylococcal kayvirus phiSA039 reveals a novel strategy that protects Staphylococcus aureus against infection by Staphylococcus pseudintermedius Siphoviridae phages

A. H. Azam, K. Kadoi, K. Miyanaga, M. Usui, Y. Tamura, L. Cui, Y. Tanji

This study identifies a novel host-recognition mechanism in the kayvirus phiSA039 that allows it to infect both Staphylococcus aureus and S. pseudintermedius by adapting its receptor and exploiting differences in WTA glycosylation.

Analysis of phage-resistant mechanisms in Staphylococcus aureus SA003 reveals a different binding mechanism for the closely related Twort-like phages phiSA012 and phiSA039

A. H. Azam, F. Hoshiga, I. Takeuchi, K. Miyanaga, Y. Tanji

This study identifies mutations in Staphylococcus aureus SA003 conferring resistance to phage phiSA012 and shows that phiSA039 uses a different binding mechanism involving beta-GlcNAc in Wall Teichoic Acid.
