3a23 Summary


Crystal Structure of beta-L-Arabinopyranosidase complexed with D-galactose

The structure was published by Ichinose, H., Fujimoto, Z., Honda, M., et al., Nishimoto, Y., Uzura, A., and Kaneko, S., in 2009 in a paper entitled "A beta-l-Arabinopyranosidase from Streptomyces avermitilis is a novel member of glycoside hydrolase family 27." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.9 Å and deposited in 2009.

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