• Chemistry

Hydrolytic enzymes: Zn-metallproteases and glycoside hydrolases. Plant biomass-derived renewable materials. Molecular evolution of oligotrophic life.

Research

My research focuses on all aspects of hydrolytic enzymes, especially Zn-metalloproteases and glycoside hydrolases in order to understand their physiological function, in disease development and molecular evolution of bacterial life in oligotrophic environments.

My research interest spans across several disciplines of biological chemistry, focusing on the following areas:

• Zn-metalloenzymes.
• Role of metalloproteases in cell signaling and cancer metastasis.
• Zn-metalloproteases in Caulobacter crescentus and Caenorhabditis elegans
• Bacterial glycoside hydrolases
• Plant biomass-derived renewable materials
• Bioinorganic chemistry/Chemical biology/Synthetic biology

Within my research, I use molecular biological/cloning techniques in bacterial and yeast expression systems to obtain the proteins of interest. Easy-to-handle eukaryotic model systems, such as C. elegans, functional genomic techniques, are employed to understand the functional significance of these metalloenzymes in eukaryotes.
