Maltose phosphorylase from Lactobacillus brevis

The structure was published by Egloff, M.-P., Uppenberg, J., Haalck, L., and Van Tilbeurgh, H., in 2001 in a paper entitled "Crystal Structure of Maltose Phosphorylase from Lactobacillus Brevis: Unexpected Evolutionary Relationship with Glucoamylases." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.15 Å and deposited in 2001.

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