The invention provides a method for making polypeptides being preferentially acylated in certain lysine ϵ-amino groups. Specifically, glucagon like protein-1 (GLP-1(7-37)) is acylated. The present invention is related to a method of producing polypeptides in transformed host cells by expressing a precursor molecule of the desired polypeptide which is to be acylated in a subsequent in

2014-03-03 · Only N-acylated peptides caused additional severe effects on the main phase transition of liposomes composed of pure phosphatidylethanolamine, while both peptide types inhibited the lamellar to hexagonal phase transition. Lipid mixtures of phosphatidylethanolamine and cardiolipin revealed anionic clustering by all peptide types.

Primarily produced by Gram-negative bacteria, acylated homoserine lactones (AHLs) are a class of small neutral lipid molecules composed of a homoserine lactone ring with an acyl chain. AHLs produced by different species of Gram-negative bacteria vary in the length and composition of the acyl side chain, which often contains 4 to 18 carbon atoms.

20 Time (min) Flg. 1 FPLC of non-acylated and fatty acylated peptides. (a) non-acylated, (b) fatty acylated.

The translocation is greatly affected by interactions between the peptides and the lipid cell membrane, which in turn is influenced by acylation of the peptides. Acetylation modification of peptides is a reversible post-translational modification process that can be expressed in both eukaryotic and prokaryotic cells. In the past few decades, many researches have been carried out on the acetylation modification of amino acids. 2001-04-02 · Tolerance induction by acylated peptides: suppression of EAE in the mouse with palmitoylated PLP peptides.

The binding energies of the anionic form of the fatty acids and the corresponding acylated glycines were identical; the energies increased by 0.8 kcal/mol per number of carbons in the acyl 1979-06-21 · Activation of lipoprotein lipase by native and acylated peptides of apolipoprotein C-II. Musliner TA, Herbert PN, Church EC. Apolipoprotein C-II, a protein found associated with all major classes of plasma lipoproteins, is a potent activator of the enzyme lipoprotein lipase. The invention provides a method for making polypeptides being preferentially acylated in certain lysine ϵ-amino groups. Specifically, glucagon like protein-1 (GLP-1(7-37)) is used. The present invention is related to a method of producing polypeptides in transformed host cells by expressing a precursor molecule of the desired polypeptide which is to be acylated in a subsequent in vitro step. 2014-03-03 · Only N-acylated peptides caused additional severe effects on the main phase transition of liposomes composed of pure phosphatidylethanolamine, while both peptide types inhibited the lamellar to hexagonal phase transition.

However, orexigenic (acylated and desacylated ghrelin and preptin) and anorexigenic (nesfatin-1 and leptin) peptide hormones of the endocrine system may play a critical role in the development of obesity by regulating the energy balance and affecting the “eating center” and “satiety center” in the paraventricular nucleus, arcuate nucleus, and nucleus of the solitary tract.

The rapid renal clearance of peptides in vivo limits this attractive platform for the treatment of a broad range of diseases that require prolonged drug half-lives. Acylated and other amphiphilic peptides are well known to self-assemble into supramolecular structures [20,21].

Lipid mixtures of phosphatidylethanolamine and cardiolipin revealed anionic clustering by all peptide types. First, we found a strong potential of those peptides to form large amyloid-like supramolecular assemblies. Second, in vivo, the large excess of cell surface membranes provides an unspecific target Figure 1 In oral drug delivery of peptide drugs, the peptide is intended to translocate across the intestinal cells and enter the bloodstream. The translocation is greatly affected by interactions between the peptides and the lipid cell membrane, which in turn is influenced by acylation of the peptides. Acetylation modification of peptides is a reversible post-translational modification process that can be expressed in both eukaryotic and prokaryotic cells.
