Conjugative T4SS have three ATPases that enable DNA processing and transport of the nucleoprotein complex to the recipient cell. In the conjugative plasmid R388, these ATPases are named TrwB, TrwK, and TrwD. Here, three different spectrophotometric assays to measure the enzymatic properties of these ATPases are described. The choice of the assay will depend on the specific requirements of each enzyme.}, organization = {Acknowledgments: This work was supported by the Spanish Ministerio de Economía y Competitividad (MINECO) grants BFU2016-78521-R (to E.C. and I.A.) and BFU2014-61823-EXP (to E.C.).}, publisher = {Springer Nature}, publisher = {Methods in Molecular Biology, 2020, 2075, 135-143}, title = {Spectrophotometric assays to quantify the activity of T4SS ATPases}, author = {Cabezón Navarro, María Elena and Arechaga Iturregui, Ignacio María}, }
