This domain family is found in bacteria and eukaryotes, and is approximately 50 amino acids in length, and the family is found in association with Pfam:PF00264. Most members are annotated as being polyphenol oxidases, and many are from plants or plastids. There is a conserved DWL sequence motif which gives the family its name.	Domain

This domain family is found in eukaryotes, and is typically between 138 and 152 amino acids in length. and the family is found in association with Pfam:PF00264. Many members are plant or plastid polyphenol oxidases, and there is a highly conserved sequence motif: KFDV, from which the name derives. This is the C-terminal domain of these oxidases.	Domain
