1b3r Summary



The structure was published by Hu, Y., Komoto, J., Huang, Y., et al., Takata, Y., Fujioka, M., and Takusagawa, F., in 1999 in a paper entitled "Crystal structure of S-adenosylhomocysteine hydrolase from rat liver." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.8 Å and deposited in 1998.

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