1fs2 Summary



The structure was published by Schulman, B.A., Carrano, A.C., Jeffrey, P.D., et al., Harper, J.W., Pagano, M., and Pavletich, N.P., in 2000 in a paper entitled "Insights into SCF ubiquitin ligases from the structure of the Skp1-Skp2 complex." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.9 Å and deposited in 2000.

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