Antiparallel four-stranded coiled coil specified by a 3-3-1 hydrophobic heptad repeat

The structure was published by Deng, Y., Liu, J., Zheng, Q., Eliezer, D., Kallenbach, N.R., and Lu, M., in 2006 in a paper entitled "Antiparallel four-stranded coiled coil specified by a 3-3-1 hydrophobic heptad repeat." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.5 Å and deposited in 2005.

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