Crystal structure of Ribonuclease Sa2

The structure was published by Sevcik, J., Dauter, Z., and Wilson, K.S., in 2004 in a paper entitled "Crystal structure reveals two alternative conformations in the active site of ribonuclease Sa2." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.507 Å and deposited in 2003.

The experimental data on which the structure is based was also deposited.

This PDB entry contains multiple copies of the structure of ribonuclease.
