Research Interests
The research is focused on the study of enzymes involved on the denitrification pathway, in the dissimilatory nitrate reduction, and on the mechanisms of enzymes that require oxygen activation, such as enzymes of the iron metabolism, desaturases and oxygenases. A series of different techniques is applied on this characterization, namely biochemical techniques, molecular biology methods and various spectroscopies (UV/visible, EPR and Mössbauer) in conjunction with fast kinetic techniques (stopped-flow and rapid-freeze quench).
