Polyphenolic protein

Polyphenolic protein

Polyphenolic proteins are proteins produced by some algae and marine invertebrates like the blue mussel, Mytilus edulis[1][2] or the polychaete Phragmatopoma californica[3] that are used as bioadhesives.[4] These proteins contain a high level of L-DOPA[3] and cystine.[1]

The blue mussel protein is called mefp-5.[5] The one for the Mediterranean mussel, Mytilus galloprovincialis, is called fp-5,[6] fp being the abbreviation for foot protein.

In the zebra mussel (Dreissena polymorpha), two different protein precursors, Dpfp-1 and Dpfp-2, have been isolated and localized in the juncture between byssus threads and adhesive plaque.[7]

Polyphenolic proteins can be polymerised in vitro using a mushroom tyrosinase.[8]
