However, the genomes of several strains of this Gram-negative bacterium code for a FAD-dependent monooxygenase (SmTetX) homologous to tetracycline destructases. This protein was recombinantly produced and its structure and function were investigated. Activity assays using SmTetX showed its ability to modify oxytetracycline with a catalytic rate comparable to those of other destructases. SmTetX shares its fold with the tetracycline destructase TetX from Bacteroides thetaiotaomicron; however, its active site possesses an aromatic region that is unique in this enzyme family. A docking study confirmed tetracycline and its analogues to be the preferred binders amongst various classes of antibiotics.</p> </div> </div> <div class="kudos-box kudos-box-with-avatar"> <h3> Why is it important? </h3> <div class="wrap-words"> <p class="preserve-line-breaks">Our results provide evidence that S. maltophilia codes for an enzyme that is capable of degrading tetracycline antibiotics, even if such a mechanism is not essential for its resistance to these antibiotics.</p> </div> </div> <div class="kudos-widget-article-readmore-btn-container"> <a class="btn btn-md btn-block blue-background" target="_blank" href="https://www.growkudos.com/articles/10.1107/s2053230x23005381?utm_medium=widget&utm_source=publication-widget">Read more on Kudos…</a> </div> <div class="with-bottom-small-margin"> <div class="inline-block"> The following have contributed to this page: </div> <div class="inline-block"> Martin Malý </div> </div> </div></div>' ,"url"));
