Crystal structure of the N-Terminus of titin

The structure was published by Marino, M., Zou, P., Svergun, D., et al., Wilmanns, M., Muhle-Goll, C., and Mayans, O., in 2006 in a paper entitled "The Ig doublet Z1Z2: a model system for the hybrid analysis of conformational dynamics in Ig tandems from titin" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.0 Å and deposited in 2005.

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

This PDB entry contains multiple copies of the structure of Titin.

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 has more than one probable quaternary state observed. For more details see the quaternary structure page.
