spacer

Zn-binding domain of the T347G mutant of human aminoacylase-I

The structure was published by Lindner, H.A., Lunin, V.V., Alary, A., Hecker, R., Cygler, M., and Menard, R., in 2003 in a paper entitled "Essential roles of zinc ligation and enzyme dimerization for catalysis in the aminoacylase-1/M20 family." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.4 Å and deposited in 2003.

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

This PDB entry contains a complex of 2 biomacromolecules, namely Aminoacylase-1.

It also contains one or more heterogenic compounds (e.g., ligands, co-factors, ions, modified amino acids, etc.); see here for a complete list.
