1bmm Summary



The structure was published by Malley, M.F., Tabernero, L., Chang, C.Y., et al., Roberts, D.G., Das, J., and Sack, J.S., in 1996 in a paper entitled "Crystallographic determination of the structures of human alpha-thrombin complexed with BMS-186282 and BMS-189090." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.6 Å and deposited in 1995.

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

This PDB entry contains a complex of 3 biomacromolecules, namely ALPHA-THROMBIN and HIRUDIN I.

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.
