Crystal structure of the intein homing endonuclease PI-SceI bound to its recognition sequence

The structure was published by Moure, C.M., Gimble, F.S., and Quiocho, F.A., in 2002 in a paper entitled "Crystal structure of the intein homing endonuclease PI-SceI bound to its recognition sequence." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 3.5 Å and deposited in 2002.

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

This PDB entry contains a complex of 3 biomacromolecules, namely PI-SceI DNA recognition region top strand, PI-SceI DNA recognition region bottom strand, and ENDONUCLEASE PI-SCEI.

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 heterotrimers.
