Accession ID	Name	Pfam Type
PF13854	Kelch motif	repeat

The kelch motif was initially discovered in Kelch (Swiss:Q04652). In this protein there are six copies of the motif. It has been shown that Swiss:Q04652 is related to Galactose Oxidase [1] for which a structure has been solved [2]. The kelch motif forms a beta sheet. Several of these sheets associate to form a beta propeller structure [3] as found in Pfam:PF00064, Pfam:PF00400 and Pfam:PF00415.
