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
A, B	PF00264	Common central domain of tyrosinase (Tyrosinase)	Common central domain of tyrosinase	This family also contains polyphenol oxidases and some hemocyanins. Binds two copper ions via two sets of three histidines. This family is related to Pfam:PF00372.	Domain
