Catalytic domain of glucoamylase from aspergillus niger complexed with tris and glycerol

The structure was published by Lee, J. and Paetzel, M., in 2011 in a paper entitled "Structure of the catalytic domain of glucoamylase from Aspergillus niger." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.9 Å and deposited in 2008.

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

The PDB entry contains the structure of Glucoamylase. This molecule has the UniProt identifier P69328 (AMYG_ASPNG)search. The sample contained 470 residues which is < 90% of the natural sequence. Out of 470 residues 458 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.
