CRYSTAL STRUCTURE OF RECOMBINANT ASCORBATE PEROXIDASE

The structure was published by Patterson, W.R. and Poulos, T.L., in 1995 in a paper entitled "Crystal structure of recombinant pea cytosolic ascorbate peroxidase." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.2 Å and deposited in 1995.

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

This PDB entry contains multiple copies of the structure of CYTOSOLIC ASCORBATE PEROXIDASE.

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.
