- ArticleMargalit R, Shaklai N.Biochim Biophys Acta. 1978 Aug 21;535(2):272-80.Canavalin is a tetramer with 6 tyrosines per subunit. In the work presented here, we have classified these tyrosines by their spectrophotometric and fluorometric pH titration and their ability to be quenched I-. Of the 6 residues, 2 were found to be exposed to the solvent. One (pK = 10.2) contributes 28% of the total fluorescence intensity; the second has a pK of 11.50, and a lower quantum yield, contributing only 16% of the total intensity. The remaining 4 residues (pK = 12.5, contributing 54% of fluorescence intensity) are buried; their titration is irreversible, requiring protein denaturation.
