Molecular mechanisms of bacterial cell division
How cells grow and divide with extraordinary accuracy is at the center of all forms of life and has been a focus of research for many decades. Even though our understanding of the underlying […]
Tuberculosis still remains a major threat for public health, with one-third of the world population latently infected, and more than one million deaths per year according to the WHO. Among the factors that have […]
Acyl-CoAs are the major metabolic carriers of carbon in living organisms. The most conserved ways to their synthesis include the oxidative decarboxylation of α-ketoacids carried out by three distinct enzymatic machineries: the pyruvate dehydrogenase […]
Type II protein secretion mechanism
Many Gram-negative bacteria secrete stably folded or even multimeric proteins across the outer membrane. The secreted substrates are often virulence factors like hydolases or toxins that contribute to the ability of bacteria to adapt […]
Structural studies of type II topoisomerases
Our main research projects focus on structural and functional studies of M. tuberculosis DNA gyrase and aim to understand the structural dynamics of DNA recognition by DNA gyrase and the quinolone resistance mechanisms […]
PknA/PknB in mycobacterial cell division
The genes pknA and pknB are located near the origin of replication in M. tuberculosis and are part of a conserved operon that also includes pstP (coding the only known Ser/Thr protein phosphatase […]
Control of glutamate metabolism in mycobacteria
We recently demonstrated the existence of a phosphorylation-dependent control of glutamate metabolism in mycobacteria, in collaboration with H. O’Hare’s group in Leicester (O’Hare et al., 2008). Our results were supported by similar observations […]
