Crystal structure of rice alpha-galactosidase

The structure was published by Fujimoto, Z., Kaneko, S., Momma, M., Kobayashi, H., and Mizuno, H., in 2003 in a paper entitled "Crystal structure of rice alpha-galactosidase complexed with D-galactose" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.5 Å and deposited in 2003.

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

The PDB entry contains the structure of alpha-galactosidase. This molecule has the UniProt identifier Q9FXT4 (AGAL_ORYSJ)search. The sample contained 362 residues which is 100% of the natural sequence. Out of 362 residues 362 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.
