Methionine, as the universal start codon, begins all mRNA sequences, however, it is sometimes removed as part of a post-translational modification. Question: What percentage of mature proteins have methionine at their N-terminus? I would appreciate an estimate from peer-reviewed literature, or, if you have a lot of experience in post-translational modification, a ballpark-type estimate would be great. Any help would be much appreciated! Bret
