Values represent mean residues per 100 residues from at least two samples. aLucas et al.,2002. bNumber in parentheses is Dopa residues +tyrosine (Tyr) residue for the total Tyr amount. Acid extracts are acetic acid soluble proteins from distal byssal threads. Purified protein refers to the RP-HPLC purified group of proteins. `TMPs' are the most abundant group of proteins found in the partially purified TMPs. `TMP's Calc.' is the calculated amino acid composition of the assembled full-length TMP-1 variant. The detection of Dopa was variable due to experimental procedure. In order to achieve accurate total Tyr compositions, only compositions in which Dopa was detected were included
