SCALLOP MYOSIN REGULATORY DOMAIN

The structure was published by Houdusse, A. and Cohen, C., in 1996 in a paper entitled "Structure of the regulatory domain of scallop myosin at 2 A resolution: implications for regulation." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.0 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 SCALLOP 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.

The molecule most likely forms heterotrimers.
