2mys Summary


PDB entry 2mys (supersedes 1mys)


The structure was published by Rayment, I., Rypniewski, W.R., Schmidt-Base, K., et al., Winkelmann, D.A., Wesenberg, G., and Holden, H.M., in 1993 in a paper entitled "Three-dimensional structure of myosin subfragment-1: a molecular motor." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.8 Å and deposited in 1996.

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

This PDB entry contains a complex of 3 biomacromolecules, namely MYOSIN.

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