1. Deputy Head of Division of Structural and Computational Biology, School of Biological Sciences,
Nanyang Technological University
2. Member of the Steering committee of the Singapore Bioimaging Consortium (SBIC)
The research group on Structure and function of molecular motors of A/Prof. G. Gruber in the Division of Structural and Computational Biology, SBS, NTU, is recognized for their expertise in determining the relationships between the structure and function of the so-called A1AO ATP synthases, V1VO ATPases, F1FO ATP synthases and AAA-ATPases. These enzymes are proposed to be the smallest biological motor proteins (nano-motor proteins). In order to get inside into the structure of these multi-subunit membrane complexes techniques like single particle analysis of electron micrographs, solution X-ray scattering, X-ray crystallography and NMR-spectroscopy are used. The functional and dynamical processes inside these enzymes are studied by fluorescence spectroscopy (e.g. FRET, FCS, intrinsic fluorescence spectroscopy) and biochemical approaches.
