Methods are provided for detecting methionine aminopeptidase (MAP) activity and for detecting inhibitors of MAP. The methods utilize a peptide comprising an N-terminal methionine which can be cleaved from the peptide by MAP, and a C-terminal detection moiety which is released by a second peptidase only...http://www.google.co.uk/patents/US20010047078?utm_source=gb-gplus-sharePatent US20010047078 - Methods for identifying inhibitors of methionine aminopeptidases
