FAMILY 13 ALPHA AMYLASE IN COMPLEX WITH ACARBOSE

The structure was published by Brzozowski, A.M. and Davies, G.J., in 1997 in a paper entitled "Structure of the Aspergillus oryzae alpha-amylase complexed with the inhibitor acarbose at 2.0 A resolution." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.98 Å and deposited in 1997.

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

The PDB entry contains the structure of TAKA AMYLASE. This molecule has the UniProt identifier P0C1B3 (AMYA1_ASPOR)search. The sample contained 478 residues which is 100% of the natural sequence. Out of 478 residues 476 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.
