C-terminally amidated
WebThis experiment used IAPP 17-37 that was N- terminally acetylated and C-terminally amidated. Two samples were prepared, one at pH 55 and the other at pH 74. Immediately after the pH was adjusted, the sample was analyzed by turbidity. An increase in turbidity indicates an increase in particle size (i.e. aggregation). The WebJul 29, 2024 · Over half of all biologically active peptides and peptide hormones are C-terminally α-amidated, which is essential for their full biological activities (Kim and Seong, 2001). In most cases, this structural feature is essential for receptor recognition, signal transduction, and ligand binding.
