Crystal structure of a POU/HMG/DNA ternary complex

The structure was published by Remenyi, A., Lins, K., Nissen, L.J., Reinbold, R., Scholer, H.R., and Wilmanns, M., in 2003 in a paper entitled "Crystal Structure of a POU/Hmg/DNA Ternary Complex Suggests Differential Assembly of Oct4 and Sox2 on Two Enhancers" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.6 Å and deposited in 2002.

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

This entry contains 8 copies of 4 unique biopolymers (complete list).
