PDB entry 1fwj (supersedes 1kau)

KLEBSIELLA AEROGENES UREASE, NATIVE

The structure was published by Pearson, M.A., Michel, L.O., Hausinger, R.P., and Karplus, P.A., in 1997 in a paper entitled "Structures of Cys319 variants and acetohydroxamate-inhibited Klebsiella aerogenes urease." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.2 Å and deposited in 1997.

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

This PDB entry contains a complex of 3 biomacromolecules, namely UREASE.

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 most likely forms heterononamer.
