For 2019 <em>S. aureus<\/em> was the leading bacterial cause of death in 135 countries (including New Zealand), being the only organism that was associated with more than 1 million deaths worldwide.(1)<br \/>\nThere is an urgent need for better diagnostic tools such as advanced imaging agents to determine where exactly the infection is located, how significant it is and if it is responding to antibiotic treatments.<br \/>\nWe create such tools by covalently targeting ten <em>S. aureus<\/em> serine hydrolase proteins (FphA-J 52-22 <em>kD<\/em>). These proteins are active during <em>S. aureus<\/em> infections, making them promising targets for diagnostics.(2) Our strategy ensures that the new diagnostic tool will have exceptional levels of specificity, negating off-target toxic effects while also offering additional therapeutic benefits due to the inhibition of the target proteins.<\/p>\n<h2>Fluorophosphonate-binding hydrolases A-J<\/h2>\n<ul>\n<li>All active in <em>S. aureus<\/em> biofilms<\/li>\n<li>Cut unknown molecules<\/li>\n<li>Cutting by activated serine (S-H-D\/E)<\/li>\n<\/ul>\n<p><a href=\"https:\/\/blogs.otago.ac.nz\/fellner\/files\/2023\/02\/Fold.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-74\" src=\"https:\/\/blogs.otago.ac.nz\/fellner\/files\/2023\/02\/Fold-300x258.jpg\" alt=\"\" width=\"300\" height=\"258\" srcset=\"https:\/\/blogs.otago.ac.nz\/fellner\/files\/2023\/02\/Fold-300x258.jpg 300w, https:\/\/blogs.otago.ac.nz\/fellner\/files\/2023\/02\/Fold-1024x882.jpg 1024w, https:\/\/blogs.otago.ac.nz\/fellner\/files\/2023\/02\/Fold-768x662.jpg 768w, https:\/\/blogs.otago.ac.nz\/fellner\/files\/2023\/02\/Fold-348x300.jpg 348w, https:\/\/blogs.otago.ac.nz\/fellner\/files\/2023\/02\/Fold.jpg 1364w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><a href=\"https:\/\/blogs.otago.ac.nz\/fellner\/files\/2023\/02\/FphH.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-75\" src=\"https:\/\/blogs.otago.ac.nz\/fellner\/files\/2023\/02\/FphH-265x300.jpg\" alt=\"\" width=\"265\" height=\"300\" srcset=\"https:\/\/blogs.otago.ac.nz\/fellner\/files\/2023\/02\/FphH-265x300.jpg 265w, https:\/\/blogs.otago.ac.nz\/fellner\/files\/2023\/02\/FphH.jpg 710w\" sizes=\"auto, (max-width: 265px) 100vw, 265px\" \/><\/a><\/p>\n<p><em>Share common fold, except N-terminal helices and first N-terminal \u03b2 strand<\/em><\/p>\n<h3><strong>General strategy:<\/strong><\/h3>\n<p>Utilisation of the serine hydrolase catalytic mechanism: Stalling the enzyme in a covalent intermediate state by introducing certain small molecules.
