The crystal structure of bovine pancreatic ribonuclease A in complex with uridine 5′-monophosphate was determined at 1.60 Å resolution. The uridine lies in the pyrimidine-specific binding site of the enzyme, with the phosphate group extended into the solvent without interacting with the protein.

In this study, the mature form of SPN48 was overexpressed in Escherichia coli and purified. The purified SPN48 protein was crystallized using 14% polyethylene glycol 8000 and 0.1 M 2-(N-morpho­lino)ethanesulfonic acid pH 6.0 as the precipitant. The crystals diffracted X-rays to 2.1 Å resolution and were suitable for structure determination.
