Crustacean Color-Change Hormone: Amino Acid Sequence and Chemical Synthesis

The blanching hormone of the prawn, Pandalus borealis , is pGlu-Leu-Asn-Phe-Ser-Pro-Gly-Trp-NH 2 . Its structure was settled by a combination of mass spectrometry and Edman-dansyl analysis of a thermolysin fragment. Confirmation of the structure was obtained by chemical synthesis from amino acids.

Description
Summary:The blanching hormone of the prawn, Pandalus borealis , is pGlu-Leu-Asn-Phe-Ser-Pro-Gly-Trp-NH 2 . Its structure was settled by a combination of mass spectrometry and Edman-dansyl analysis of a thermolysin fragment. Confirmation of the structure was obtained by chemical synthesis from amino acids. This neurosecreted hormone is active in picogram amounts when tested in shrimps.
