ALPHA-AMYLASE FROM BACILLUS SUBTILIS COMPLEXED WITH MALTOPENTAOSE

The structure was published by Fujimoto, Z., Takase, K., Doui, N., Momma, M., Matsumoto, T., and Mizuno, H., in 1998 in a paper entitled "Crystal structure of a catalytic-site mutant alpha-amylase from Bacillus subtilis complexed with maltopentaose." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.5 Å and deposited in 1998.

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

The PDB entry contains the structure of ALPHA-1,4-GLUCAN-4-GLUCANOHYDROLASE. This molecule has the UniProt identifier P00691 (AMY_BACSU)search. The sample contained 425 residues which is < 90% of the natural sequence. Out of 425 residues 425 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.
