KinaFrag is an integrated database to explore the kinase-ligand fragment interaction space. It contains 31464 kinase ligand fragments, 7783 crystal structures of kinase-ligand fragment complex, involving 894 kinase ligand binding cleft structures and 5066 kinase ligand binding sub-pocket structures. Each fragment record contains detailed information on chemical identification, physicochemical properties, binding information, similarity structures and references, which could be used for the exploration of known kinase-ligand fragment interaction space. The high quality data are mainly collected from existing electronic databases, and all the fragments are generated with our experience can be traced back to the original source. In addition, we provide a fragment-linking workflow to explore the unknown kinase-ligand fragment interaction space. Comprehensive data, user-friendly interface allow user to browse, search, retrieve or extract information within KinaFrag, and may facilitate selective kinase inhibitors design via fragment-based drug design.
