Marine mussels secrete a byssus in order to attach to solid surfaces in the sea. The polyphenolic protein is the "glue" in the adhesive plaques of the byssus. In Mytilus californianus, the polyphenolic protein has an apparent molecular weight of 85,000 +/- 5,000 and is rich in the amino acids lysine, 3,4-dihydroxyphenylalanine, serine, threonine, and hydroxyproline. In composition it resembles the polyphenolic protein of M. edulis (Mr = 125,000), although the M. edulis protein contains significantly less isoleucine and more alanine. Tryptic digestion of M. californianus polyphenolic protein revealed two types of repeating decapeptides (1) (Ser/Thr)-Thr-(Tyr/Dopa)-Hyp-Hyp-Thr-Dopa-Lys-Hyp-Lys and (2) Ile-(Thr/Ser)-(Tyr/Dopa)-Hyp-Hyp-Thr-Dopa-Lys-Hyp-Lys. Residues 2 to 8 are identical with residues 4-10 in M. edulis decapeptides.
海洋贻贝分泌足丝以便附着在海洋中的固体表面。多酚蛋白是足丝附着斑中的“胶水”。在加州贻贝中，多酚蛋白的表观分子量为85,000±5,000，富含赖氨酸、3,4-二羟基苯丙氨酸、丝氨酸、苏氨酸和羟脯氨酸。在组成上，它类似于紫贻贝的多酚蛋白（Mr = 125,000），尽管紫贻贝蛋白中的异亮氨酸含量明显较少，丙氨酸含量较多。对加州贻贝多酚蛋白进行胰蛋白酶消化后，发现了两种重复的十肽：(1)（丝氨酸/苏氨酸）-苏氨酸-（酪氨酸/多巴）-羟脯氨酸-羟脯氨酸-苏氨酸-多巴-赖氨酸-羟脯氨酸-赖氨酸和(2)异亮氨酸-（苏氨酸/丝氨酸）-（酪氨酸/多巴）-羟脯氨酸-羟脯氨酸-苏氨酸-多巴-赖氨酸-羟脯氨酸-赖氨酸。第2至8位残基与紫贻贝十肽中的第4至10位残基相同。
