1wbg Summary



The structure was published by Hartshorn, M.J., Murray, C.W., Cleasby, A., Frederickson, M., Tickle, I.J., and Jhoti, H., in 2005 in a paper entitled "Fragment-Based Lead Discovery Using X-Ray Crystallography" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.2 Å and deposited in 2004.

The experimental data on which the structure is based was not deposited.

This PDB entry contains a complex of 3 biomacromolecules, namely THROMBIN LIGHT CHAIN, THROMBIN HEAVY CHAIN, and HIRUGEN.

It also contains one or more heterogenic compounds (e.g., ligands, co-factors, ions, modified amino acids, etc.); see here for a complete list.

The molecule most likely forms heterotrimers.
