Abstract
Methods of obtaining N-terminal methionine-free proteins are described. The methods employ a novel enzyme, E. coli methionine aminopeptidase either in vitro or in vivo. For in vivo application, plasmid-borne DNA encoding the peptidase is transformed into a bacterial host which produces the desired protein.
