ECHO grant for Marcellus Ubbink
Encountercomplex_simple.jpg

An ECHO grant has been awarded to Marcellus Ubbink for research in dynamic protein complexes. The project is aimed at manipulating a protein interface to change the encounter state of the complex. This state is the essential prelude to forming an active protein-protein complex. The project will elucidate how important electrostatic interactions are for homing in on the final binding site.
