Projektbeschreibung
Neue molekulare Targets gegen Mykobakterien
Antimikrobielle Resistenz breitet sich immer weiter aus und betrifft verschiedene Bakterien, wie zum Beispiel das Mycobacterium tuberculosis. Darum müssen dringend neue wirksame Medikamente entwickelt werden. Das von der EU finanzierte Projekt deCrYPtion schlägt die Proteinfamilie der Cytochrome P450 (CYP) als Ansatzpunkt für eine neue Behandlungsstrategie vor. Hauptziel ist, physiologische Informationen über verschiedene CYP zu liefern, die bisher noch nicht funktionell charakterisiert worden sind. Die Forschenden werden die CYP analysieren, die in der Mykobakterienart kodiert sind und ihre Funktion spezifischen biologischen Pfaden zuordnen. Dank der Ergebnisse von deCrYPtion werden sich neue Wirkstofftargets gegen Mykobakterien finden lassen.
Ziel
More than 190 species belong to the Mycobacterium genus. Among those, several are pathogenic to human and animals. The high number of human lives lost and the economic consequences of livestock infection are important incentives in the control and eradication of the responsible organisms. M. tuberculosis, one of the causative agents of tuberculosis (TB), is the most problematic representative: in 2016, 1.7 million deaths worldwide have been attributed to TB. Like for other infectious organisms, antibiotic resistances have appeared in Mycobacterium. Thus, there is a fundamental need to develop new antimycobacterial drugs. The inhibition of enzymes belonging to the Cytochrome P450 (CYP) protein family has been shown to suppresses the growth of several Mycobacterium species, making CYPs targets for drug development. Unfortunately, most CYPs are considered orphan: proteins for which no physiological function is known. The deCrYPtion action aims to define the physiological function of a selected set of mycobacterial CYPs. It will prove determinant in the development of new antibiotics. I will perform a large-scale comparative genomics analysis of the CYPs encoded by Mycobacterium species, in order to define orthologous groups and identify, for each, conserved partners and pathway context. This approach is extremely powerful (even if not frequently used) and allow to propose physiological functions, based on the information obtained. Specific CYPs to be characterized will be selected based on a set of stringent considerations, including their potential as drug targets. A preliminary analysis illustrates the approach that will be used. A combination of complementary biochemical, genetics and physiological experiments will be performed to validate the hypotheses generated. deCrYPtion will be undertaken within the Centre for Cytochrome P450 Biodiversity, under the supervision of Prof Steven Kelly, at Swansea University (Wales, United Kingdom).
