Protein sequence space is vast, the possibilities are astronomical, yet only a tiny fraction of it is sampled by existing proteins. We mine evolutionary information from millions of genomes to understand how protein families evolve, and what rules govern their functional and structural divergence. We focus not only on genetic mutations but also on phenotypic mutations, i.e mutations introduced by transcriptional and translational machinery. We wish to answer how proteins remain robust to mutations and facilitate innovations at the same time. We combine bioinformatics, modelling and experimental evolution to answer fundamental questions about molecular evolution.
