2bkh Summary



The structure was published by Menetrey, J., Bahloul, A., Wells, A., et al., Morris, C., Sweeney, H.L., and Houdusse, A., in 2005 in a paper entitled "The Structure of the Myosin Vi Motor Reveals the Mechanism of Directionality Reversal" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.4 Å and deposited in 2005.

The experimental data on which the structure is based was also deposited.

This PDB entry contains a complex of 2 biomacromolecules, namely UNCONVENTIONAL MYOSIN and CALMODULIN.

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 heterodimers.
