Competing forms of protein-protein association and DNA binding exhibited by BrxC from the BREX phage restriction system

Alex J Kaiser, Jennifer J. Readshaw, Lindsey Doyle, Maria Puiu, Abigail Kelly, Sydney F. McGuire, Julieta Peralta Acosta, Duc Vu, Andrew Nelson, Darren L. Smith, Lidia Araújo‐Bazán, Ernesto Arias‐Palomo, Yvette A. Luyten, Barry L. Stoddard, Tim R. Blower, Brett K. Kaiser

This study investigates the structural and functional properties of BrxC, a conserved AAA+ ATPase in the BREX phage restriction system, revealing its role in mediating competing protein associations and DNA binding that regulate host methylation and phage restriction.

PglZ from Type I BREX phage defence systems is a metal-dependent nuclease that forms a sub-complex with BrxB

Jennifer J. Readshaw, Lindsey Doyle, Maria Puiu, Abigail Kelly, Andrew Nelson, Alex J Kaiser, Sydney F. McGuire, Julieta Peralta Acosta, Darren Smith, Barry L. Stoddard, Brett K. Kaiser, Tim R. Blower

This study identifies and characterizes the PglZ:BrxB sub-complex of BREX phage defence systems, revealing PglZ as a metal-dependent nuclease that contributes to phage defence.
