We designate the GH-releasing peptide ‘ghrelin’ (ghre is Peptide autoinducers usually result from posttranslational modification of a larger precursor molecule. In many Gram-positive bacteria, secretion of peptides requires specialized export mechanisms. For example, some peptide autoinducers are secreted by ATP-binding cassette transporters that couple proteolytic processing and cellular export. 2018-05-14 · Examples of acylated peptides with extended half-lives are insulin detemir that has a myristic acid (C14) conjugated to the B29 lysine, and liraglutide, a GLP-1 analogue acylateded with a palmetic acid (C16) .
