CATECHOL OXIDASE FROM IPOMOEA BATATAS (SWEET POTATOES) IN THE NATIVE CU(II)-CU(II) STATE

The structure was published by Klabunde, T., Eicken, C., Sacchettini, J.C., and Krebs, B., in 1998 in a paper entitled "Crystal structure of a plant catechol oxidase containing a dicopper center." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.7 Å and deposited in 1998.

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

This PDB entry contains multiple copies of the structure of PROTEIN (CATECHOL OXIDASE).

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 has more than one probable quaternary state observed. For more details see the quaternary structure page.
