To better understand CPT we probe structure &amp; function of other plasmid-encoded proteins. <\/p>\n\n\n\n<p>For e.g resistance to penicillins, &amp; vancomycin have been found on the pSK41\/pGO1-family of conjugative plasmids. pSK41\/pGO1-family plasmids also encode the conserved gene orf86. We found that the orf86 protein can repress transcription of replication protein Rep.<\/p>\n\n\n\n<p>orf86 is a cryptic regulator of copy number, so we named it Cop. We determined the crystal structure of Staphylococcus aureus pSK41 Cop. Together with binding data, it revealed a possible tetrameric binding mode (dimer of dimers) to the Rep promoter site on the plasmid.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/pages.vassar.edu\/kmclaughlin\/files\/2024\/01\/Screenshot-2023-11-29-at-10.36.09-AM.png\" alt=\"\" class=\"wp-image-793\" width=\"540\" height=\"375\" \/><figcaption class=\"wp-element-caption\">Figure 3, Sarosh et. al 2023<\/figcaption><\/figure>\n<\/div>\n\n\n<p>We are grateful to our collaborators in the <strong>Firth Lab<\/strong> at the University of Sydney and the <strong>Redinbo Lab<\/strong> at the University of North Carolina Chapel Hill (UNC-CH), as this work was started during Dr. McLaughlin&#8217;s postdoctoral work at UNC-CH.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/pages.vassar.edu\/kmclaughlin\/files\/2024\/01\/Screenshot-2023-11-29-at-10.35.54-AM.png\" alt=\"\" class=\"wp-image-795\" width=\"643\" height=\"684\" srcset=\"https:\/\/pages.vassar.edu\/kmclaughlin\/files\/2024\/01\/Screenshot-2023-11-29-at-10.35.54-AM.png 791w, https:\/\/pages.vassar.edu\/kmclaughlin\/files\/2024\/01\/Screenshot-2023-11-29-at-10.35.54-AM-282x300.png 282w, https:\/\/pages.vassar.edu\/kmclaughlin\/files\/2024\/01\/Screenshot-2023-11-29-at-10.35.54-AM-768x818.png 768w\" sizes=\"auto, (max-width: 643px) 100vw, 643px\" \/><\/figure>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>So excited to tell you about our latest paper published in Plasmid!
