Hydrophilic residues at position 3 highlight unforeseen features of the fMLP receptor pocket
摘要:
The peptides for-Met-Leu-Tyr-OMe, for-Met-Leu-Ght-OMe, for-Met-Leu-Asp-OMe and for-Met-Leu-Ser-OMe were synthesized to investigate the importance of a hydrophilic side chain of the residue at position 3 on biological activities of human neutrophils. A number of in vitro essays were carried out, including: chemotaxis, superoxide anion production, lysozyme release and receptor binding. Our results highlight that for-Met-Leu-Asp-OMe acts as a full agonist with a higher efficacy than formyl-Met-Leu-Phe-OMe, the tripeptide normally used as a model chemoattractant for the study of cell functions. The other analogs show efficacies that are in the same range or a little less than the prototype. The main point emerging from this study is that the role of Phe substitution needs to be re-hypothesised. (C) 2003 Elsevier Science B.V All rights reserved.

essential for bacterial growth. Methionine hydroxamicacid derivatives were found to inhibit recombinant Escherichia coli peptide deformylase activity containing either zinc or cobalt. The binding of methionine hydroxamate and hydrazide inhibitors to cobalt-substituted deformylase caused spectral changes consistent with the formation of a pentacoordinate metal complex similar to that of actinonin,
