1kwb Summary


Crystal structure of the His145Ala mutant of 2,3-dihydroxybipheny dioxygenase (BphC)

The structure was published by Sato, N., Uragami, Y., Nishizaki, T., et al., Masai, E., Fukuda, M., and Senda, T., in 2002 in a paper entitled "Crystal Structures of the Reaction Intermediate and its Homologue of an Extradiol-cleaving Catecholic Dioxygenase" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.0 Å and deposited in 2002.

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