In this talk we will briefly introduce the Department of Theoretical Chemistry and Biology at KTH, Stockholm and then exemplify some ongoing work in computational biology taking place in the department. We highlight recent work on   protein-ligand binding, in particular water-mediated activation mechanisms. We discuss modeling of protein structures for structure-based drug design, exemplified by modeling the carbohydrate synthesis isolated from oomycetes pathogens. In the later part of the talk we outline our multi-scale modeling techniques for designing molecular probes in confined bio-environments like proteins, DNA and cell membranes. We use a so-called integrated approach where the system is sampled by quantum or classical molecular dynamics generating trajectories out of which system conformations are sampled and extracted for use in the modeling of the properties or spectra. The latter calculations involve multi-scale modeling in terms of combining quantum mechanics (QM) with molecular mechanics (MM) and the polarizable continuum (PCM) models, where full coupling in terms of intermolecular interactions are accounted for in generating the properties. Sample calculations for molecular probes in proteins and cell membranes will be given.
