A carotenoprotein containing canthaxanthin (Crangon crangon) and astaxanthin (Palaemon adspersus) as the prosthetic group was purified from the body of two species of shrimp from the Baltic Sea. The protein forming the complexes with the above- mentioned ketocarotenoids in these shrimps were found to contain 17 amino acids, mainly glutamine, lysine in Crangon crangon and glutamine, aspargine in Palaemon adspersus. There was little cysteine found in the protein of the two shrimp species.
