Abstract
Phosphopeptides can be identified by ion spray mass spectrometry. The method was tested with phosphokemptide and with a proteolytic digest of one subunit (δ-subunit) of the nicotinic acetylcholine receptor. In the latter one peptide containing tyrosine phosphate, one with two serine phosphates, and two different peptides each containing one serine phosphate were unambiguously identified. Thus it is proven that ion spray mass spectrometry can be applied for the localization of phosphorylation sites in a known primary structure.
