Dark blue or violet chromoproteins were isolated from the ovaries of marine snails Haliotis discus hannai, Chlorostoma lischkei, Omphalius pfeifferi, and Turbo marmorata by ammonium sulfate fractionation and Sepharose 4B gel filtration. The chromoprotein was found to be the major pigment in each of these ovaries. These chromoproteins had similar u. v. and visible absorption spectra, their molecular weights were 500, 000-700, 000 and their sedimentatin coefficients were 16-18 S. Chromophores were readily liberated from the chromoproteins by the HCI-acetone treamtment and their methyl esters were then prepared. The chromophore of the chromoprotein of T. marmorata was identified as turboverdin on the basis of u. v. and visible spectra and TLC, while those of the other three species were violin-type bile pigments. In all cases, the linkage between chromophore and protein moiety was non-covalent.
