InterPro domain: IPR041602

This entry represents the C-terminal domain of quercetin 2,3-dioxygenase (also known as quercetinase), such as the YhhW protein from E. coli. This is one of the two cupin domains that make up the protein [ 1 ]. Proteins containing this domain also include the Pirin-like protein, YhaK, from E. coli [ 2 ].
