Binding Database. BindingDB is a public, web-accessible database of measured binding affinities, focusing chiefly on the interactions of protein considered to be drug-targets with small, drug-like molecules.
BindingDB contains 1,009,290 binding data, for 6,589 protein targets and 427,325 small molecules. There are 2046 protein-ligand crystal structures with BindingDB affinity measurements for proteins with 100% sequence identity, and 5815 crystal structures allowing proteins to 85% sequence identity.
