TLDR
An acid-soluble protein was extracted and purified from the phenol gland located in the byssus-secreting foot of the fouling marine mussel, and its composition and its sticky tendencies in vitro strongly suggest that it contributes to byssal adhesion.Abstract:
The fouling marine mussel Mytilus edulis attaches itself to various substrates by spinning byssal threads, the adhesive discs of which are rich in the amino acid 3,4-dihydroxyphenylalanine (dopa). An acid-soluble protein was extracted and purified from the phenol gland located in the byssus-secreting foot of the animal. This protein is highly basic and contains large amounts of lysine, dopa, and 3- and 4-hydroxyproline. The composition of this protein and its sticky tendencies in vitro strongly suggest that it contributes to byssal adhesion.read more

A reversible wet/dry adhesive inspired by mussels and geckos
TL;DR: A hybrid biologically inspired adhesive consisting of an array of nanofabricated polymer pillars coated with a thin layer of a synthetic polymer that mimics the wet adhesive proteins found in mussel holdfasts is reported, useful for reversible attachment to a variety of surfaces in any environment.

Variations in Coupled Water, Viscoelastic Properties, and Film Thickness of a Mefp-1 Protein Film during Adsorption and Cross-Linking: A Quartz Crystal Microbalance with Dissipation Monitoring, Ellipsometry, and Surface Plasmon Resonance Study
TL;DR: It is shown how quantitative data about the thickness, shear elastic modulus, and shear viscosity of the protein film can be obtained with the QCM-D technique, even beyond the Sauerbrey regime, if frequency (f) and energy dissipation (D) measurements measured at multiple harmonics are combined with theoretical simulations using a Voight-based viscoelastic model.

Complete amino acid analysis of proteins from a single hydrolysate.
TL;DR: An analytical procedure which affords the precise amino acid composition of a protein or a peptide from a single hydrolysate is described and the values of all amino acids, including tryptophan and half-cystine, were close to the expected theoretical values for the proteins examined.
