Crytsal structure of isoaspartyl dipeptidaseCrytsal structure of isoaspartyl dipeptidase
Structural highlights
1po9 is a 2 chain structure with sequence from Escherichia coli. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
IADA_ECOLI Catalyzes the hydrolytic cleavage of a subset of L-isoaspartyl (L-beta-aspartyl) dipeptides. Used to degrade proteins damaged by L-isoaspartyl residues formation. The best substrate for the enzyme reported thus far is iso-Asp-Leu.[1][2][3][4]
