1sur Summary



The structure was published by Savage, H., Montoya, G., Svensson, C., Schwenn, J.D., and Sinning, I., in 1997 in a paper entitled "Crystal structure of phosphoadenylyl sulphate (PAPS) reductase: a new family of adenine nucleotide alpha hydrolases." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.0 Å and deposited in 1998.

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

The PDB entry contains the structure of PAPS REDUCTASE. This molecule has the UniProt identifier P17854 (CYSH_ECOLI)search. The sample contained 215 residues which is < 90% of the natural sequence. Out of 215 residues 214 were observed and are deposited in the PDB.

The molecule most likely forms homodimers.
