1b0i Summary



The structure was published by Aghajari, N., Feller, G., Gerday, C., and Haser, R., in 1998 in a paper entitled "Structures of the psychrophilic Alteromonas haloplanctis alpha-amylase give insights into cold adaptation at a molecular level." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.4 Å and deposited in 1998.

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

The PDB entry contains the structure of PROTEIN (ALPHA-AMYLASE). This molecule has the UniProt identifier P29957 (AMY_PSEHA)search. The sample contained 453 residues which is < 90% of the natural sequence. Out of 453 residues 447 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.
