1ima Summary



The structure was published by Bone, R., Frank, L., Springer, J.P., et al., Broughton, H.B., Baker, R., and Fletcher, S.R., in 1994 in a paper entitled "Structural analysis of inositol monophosphatase complexes with substrates." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.3 Å and deposited in 1994.

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