Peptides belonging to the CHH/MIH/GIH-family of crustacean hormones were isolated from acetic acid extracts of sinus glands isolated from eyestalks of the shrimp, Penaeus vannamei. The peptides were isolated by chromatography and molecular weights determined by MALDI mass spectrometry. Peptides in the range of 7-9 kDa and containing three disulfide bridges were selected for amino acid sequence analysis. Three peptides with the requisite properties were present in sufficient amounts for sequence analysis. Two peptides had unique sequences similar to CHH/MIH/GIH peptides from other crustaceans. A third peptide seemed to be a truncated form of one of the previous sequences. © 2000 Elsevier Science Inc.
