Beta-Amylase from Bacillus cereus var. mycoides in Complex with alpha-EBG

The structure was published by Oyama, T., Miyake, H., Kusunoki, M., and Nitta, Y., in 2003 in a paper entitled "Crystal Structures of beta-Amylase from Bacillus cereus var. mycoides in Complexes with Substrate Analogs and Affinity-Labeling Reagents" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.1 Å and deposited in 2002.

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