Wild Type pI258 S. aureus arsenate reductase

The structure was published by Messens, J., Martins, J.C., Van Belle, K., et al., Willem, R., Wyns, L., and Zegers, I., in 2002 in a paper entitled "All intermediates of the arsenate reductase mechanism, including an intramolecular dynamic disulfide cascade." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.01 Å and deposited in 2002.

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

The PDB entry contains the structure of arsenate reductase. This molecule has the UniProt identifier P0A006 (ARSC_STAAU)search. The sample contained 131 residues which is 100% of the natural sequence. Out of 131 residues 130 were observed and are deposited in the PDB.

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 is most likely monomeric.
