Polyphenolic proteins

Patent Pending The small family of proteins that are sometimes referred to as polyphenolic proteins are produced by some marine invertebrates like the blue mussel, Mytilus edulis[1] by some algae'[citation needed], and by the polychaete Phragmatopoma californica.[2] These proteins contain a high level of a post-translationally modified—oxidized—form of tyrosine, L-3,4-dihydroxyphenylalanine (levodopa, L-DOPA)[2] as well as the disulfide (oxidized) form of cysteine (cystine).
