With many genomes sequenced, a pressing challenge in biology is predicting the function of the proteins that the genes encode. When proteins are unrelated to others of known activity, bioinformatics inference for function becomes problematic. It would thus be useful to interrogate protein structures for function directly. Here, we predict the function of an(More)
Isoaspartyl dipeptidase from Escherichia coli functions in protein degradation by catalyzing the hydrolysis of beta-L-isoaspartyl linkages in dipeptides. The best substrate for the enzyme reported thus far is iso-Asp-Leu. Here we report the X-ray analysis of the enzyme in its resting state and complexed with aspartate to 1.65 and 2.1 A resolution,(More)
