Protein conformational changes determined by matrix-assisted laser desorption mass spectrometry.

Abstract

It is shown that simultaneously to the unfolding of hen egg white lysozyme and horse heart cytochrome c the sequential conformational changes and molten globule states can be detected by the combination of proteolysis and matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS). This is demonstrated by the differences among the products and… (More)
