STRUCTURE OF INORGANIC PYROPHOSPHATASE

The structure was published by Heikinheimo, P., Lehtonen, J., Baykov, A., Lahti, R., Cooperman, B.S., and Goldman, A., in 1996 in a paper entitled "The structural basis for pyrophosphatase catalysis." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.2 Å and deposited in 1996.

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