1fa0 Summary



The structure was published by Bard, J., Zhelkovsky, A.M., Helmling, S., Earnest, T.N., Moore, C.L., and Bohm, A., in 2000 in a paper entitled "Structure of yeast poly(A) polymerase alone and in complex with 3'-dATP." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.6 Å and deposited in 2000.

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