This can be very hard to do because quite a few proteases are promiscuous and will cut substrates solely based on masking of the polypeptide within the structure of the protein. Typically these proteases will not stop cutting at a single nick - they often proceed until they can't 'dig into' a burie

Hi Tom, You can try the MEROPS database. There is a search feature called "What peptidases can cleave this bond". http://merops.sanger.ac.uk/cgi-bin/specsearch.pl Cheers, Jack On Thu, Mar 31, 2011 at 6:59 AM, Brett, Thomas wrote: > Hi all: > I was wondering if anyone had any tips on identify

Hi all: I was wondering if anyone had any tips on identifying proteases. I have a protein for which I know the proteolytic cleavage site. What are the best ways to identify the protease that does the cutting either: 1) bioinformatically (i.e., a good database to search using the cleavage site or
