Structure of a Synaptic gamma-delta Resolvase Tetramer Covalently linked to two Cleaved DNAs

The structure was published by Li, W., Kamtekar, S., Xiong, Y., Sarkis, G.J., Grindley, N.D., and Steitz, T.A., in 2005 in a paper entitled "Structure of a synaptic gamma delta resolvase tetramer covalently linked to two cleaved DNAs." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 3.4 Å and deposited in 2005.

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

This entry contains 16 copies of 4 unique biopolymers (complete list).
