A peptide with N-terminal histidine and C-terminal isoleucine amide (PHI) and vasoactive intestinal peptide (VIP) are copackaged in myenteric neurones of the guinea pig ileum.
When cytoplasmic extracts of the myenteric plexus of guinea pig ileum are submitted to centrifugal density gradient separation in a zonal rotor, conditions which separate storage particles containing substance P, somatostatin and VIP from each other, PHI copurifies with VIP. The two immunoreactivities cannot be separated by particle exclusion chromatography, which depends on size rather than de...

متن کاملBiosynthesis of the C-terminal amide in peptide hormones.
Recent developments in the study of peptide amidation are reviewed. The main areas covered are assay procedures, purification of amidating enzymes, co-factors and regulation, mechanism and specificity of the amidating reaction, and multiple forms of the amidating enzyme and glycosylation. Discussion is presented on aspects that are poorly understood and new areas open to investigation are indic...
