1sx5 Summary


K38A EcoRV bound to cleaved DNA and Mn2+: P1 crystal form

The structure was published by Horton, N.C. and Perona, J.J., in 2004 in a paper entitled "DNA cleavage by EcoRV endonuclease: Two metal ions in three metal ion binding sites" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.5 Å and deposited in 2004.

The experimental data on which the structure is based was not deposited.

This PDB entry contains a complex of 3 biomacromolecules, namely 5'-D(*AP*AP*AP*GP*AP*T)-3', 5'-D(P*AP*TP*CP*TP*T)-3', and Type II restriction enzyme EcoRV.

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 heterohexamers.
