Edman Degradation and Protein Sequencing: Pfu Methionine Aminopeptidase

Pfu Methionine Aminopeptidase is a thermostable methionine aminopeptidase isolated from Pyrococcus furiosus and expressed as a recombinant protein. It specifically liberates the N-terminal methionine residue from proteins and peptides during Edman degradation, enabling protein sequencing.
