title: Three more novel FMRFamide-like neuropeptide sequences from the eyestalk of the giant freshwater prawn Macrobrachium rosenbergii.
abstract: In addition to five FMRFamide-like peptides (FLPs) previously isolated from the eyestalk of the giant freshwater prawn Macrobrachium rosenbergii (16), three more new FLPs (Mar-FLP6-8) were identified from minor immunoreactive fractions of 5,000 eyestalk extracted in methanol/acetic acid/water: DGGRNFLRFamide, GYGDRNFLRFamide and VSHNNFLRFamide. These three peptides share 5-6 common residues at the C-terminus with Mar-FLP1,2 and 3. This evidence reveals that the structural diversity and complexity of the FLP family in M. rosenbergii are similar to that found in other invertebrate species.
