1pbg Summary



The structure was published by Wiesmann, C., Beste, G., Hengstenberg, W., and Schulz, G.E., in 1995 in a paper entitled "The three-dimensional structure of 6-phospho-beta-galactosidase from Lactococcus lactis." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.3 Å and deposited in 1995.

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