HOMCOS: a server to predict interacting protein pairs and interacting sites by homology modeling of complex structures.

abstract：:Robust methods to detect DNA-binding proteins from structures of unknown function are important for structural biology. This paper describes a method for identifying such proteins that (i) have a solvent accessible structural motif necessary for DNA-binding and (ii) a positive electrostatic potential in the region of ...
