The Regulatory Relationship Of Transcriptional Regulators Msab And Cody In Capsule Production In Staphylococcus Aureus, Brittany L. Trunell
Honors Theses
There are many transcriptional regulators found in pathogenic Staphylococcus aureus. Many of these regulators are essential for the organism’s ability to switch from commensal form to the virulent pathogenic form. One of these main regulators is CodY. This regulator has been shown to be responsive to nutrient availability during phases of growth. Additionally, we have recently found that MsaB, the only protein coding ORF of the msaABCR operon, is a putative co-regulator of capsule along with CodY. To explore these regulator interactions, we produced mutations of codY and msaABCR individually and a double mutation of msaABCR/ codY. We have observed …
