Crystal structure of native alpha-amylase from Bacillus sp. KR-8104

The structure was published by Alikhajeh, J., Khajeh, K., Ranjbar, B., Naderi-Manesh, M., Naderi-Manesh, H., and Chen, C.J., in in a paper entitled "Crystal structure of native alpha-amylase from Bacillus sp. KR-8104" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.78 Å and deposited in 2008.

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

The PDB entry contains the structure of alpha-amylase. This molecule has the UniProt identifier B3GQD0 (B3GQD0_9BACI)search. The sample contained 422 residues which is < 90% of the natural sequence. Out of 422 residues 422 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.
