| Abstract: |
The laboratory of Microbiology studies the following topics:
- physiology of mesophilic and thermophilic microorganisms;
- relationships between structure and function in proteins and enzymes;
- biosynthesis and function of the modified nucleosides of transfer RNA.
Within the marine field, the group studies the M42 aminopeptidase enzyme in the thermophilic bacterium Thermotoga maritima, originally isolated from a deep-sea hydrothermal vent. The group focuses on its oligomeric state transition, the structural and functional role of a conserved aspartate residue in the catalytic site, and how metal cofactors drive the dimer-dodecamer transition of the enzyme. The research utilises X-ray crystallography and protein analysis techniques to investigate the molecular characteristics and mechanisms of this enzyme. |
