Enhancing the intensities of lysine-terminated tryptic peptide ions in matrix-assisted laser desorption/ionization mass spectrometry.

R L Beardsley1, J A Karty, J P Reilly.   

Abstract

Tryptic digests of three proteins are reacted with O-methylisourea in order to convert lysine residues to homoarginines. The resulting homoarginine-terminated peptides exhibit more intense MALDI mass spectral peaks than their lysine-terminated predecessors. This simple chemical reaction should therefore facilitate protein sequencing and mass mapping. Copyright 2000 John Wiley & Sons, Ltd.
