Probing of Structure and Function of Proteins by Mass Spectrometry -Analysis of Structure and Function of a Protein by the pH Titration Using ESI-MS

Autor: Kazuo Hirayama

Publikováno v: Journal of the Mass Spectrometry Society of Japan. 58:155-165

An analysis of the pH-dependent dissociation and denaturation of a heterodimeric protein is described. Electrospray ionization mass spectrometry (ESI-MS) was utilized to analyze the dissociation and denaturation of the heterodimeric yeast killer toxi
