DEACETOXYCEPHALOSPORIN C SYNTHASE (WITH A N-TERMINAL HIS-TAG) IN COMPLEX WITH FE(II) AND AMPICILLIN

The structure was published by Oster, L.M., Terwisscha Van Scheltinga, A.C., Valegard, K., et al., Dubus, A., Hajdu, J., and Andersson, I., in 2004 in a paper entitled "Conformational Flexibility of the C Terminus with Implications for Substrate Binding and Catalysis Revealed in a New Crystal Form of Deacetoxycephalosporin C Synthase" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.7 Å and deposited in 2004.

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

The PDB entry contains the structure of DEACETOXYCEPHALOSPORIN C SYNTHASE. This molecule has the UniProt identifier P18548 (CEFE_STRC2)search. The sample contained 331 residues which is 100% of the natural sequence. Out of 331 residues 269 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.
