Role Of The Pkna And Pknb Kinases In Mycobacterium Tuberculosis, Tripti Anandan
Role Of The Pkna And Pknb Kinases In Mycobacterium Tuberculosis, Tripti Anandan
Wayne State University Dissertations
To respond to environmental changes, M. tuberculosis possesses eleven "eukaryotic-type" Ser/Thr protein kinases. The aim of the study described in this dissertation was to identify role of two of these kinases; PknA and PknB that are essential in M. tuberculosis. Two approaches are described to screen for potential in vivo substrates of PknA/PknB. First approach is based on proteomic search by over-expressing PknA/PknB in M. tuberculosis. Proteomic search led to identification of proteasome to be a substrate of PknA and PknB in M. tuberculosis. Furthermore, I demonstrate that the phosphorylation of PrcA and PrcB by PknA regulates processing of Pre-PrcB. …
Role Of Phosphoylation Of The Mycobacterium Tuberculosis Proteasome In Oxidative Stress Response And Regulation Of Homoserine Kinase (Thrb) In Corynebacterium Glutamicum, Heather Baun
Wayne State University Theses
Part 1:
One-third of the world's population is infected with the latent form of Mycobacterium tuberculosis. M. tuberculosis must be able to control this latent even in response to nitrosative and oxidative stress conferred by the host. It is not well known how M. tuberculosis controls this state.
One possibility for this control is through its eleven eukaryotic-like serine/threonine protein kinases. Our lab has focused research on two eukaryotic-like ser/thr protein kinases, PknA and PknB. It has been found that PknA expression may affect the stability or the assembly of the proteasome complex, which is essential for M. tuberculosis to …
