A fully automated, user-independent method is described for computer-mediated interpretation of data derived by mass spectrometry of an experimental peptide to identify and characterize a corresponding peptide sequence in a peptide database. The method identifies the corresponding sequence if it is present in the database, without the need for a skilled observer to choose from amongst a list of possible matches. By using an automated back-read process, the present method can uniquely identify a corresponding peptide sequence in a database based on a single matching peptide sequence. The method also permits mapping of mass spectral data to sequences in peptide or nucleotide databases for unambiguous identification of exons; determining a correct reading frame; identifying artefacts and errors in sequences; identifying mutations and polymorphisms; identifying post-translational modifications; and identifying exon-intron boundaries.

An intronic, self-splicing riboswitch is configured for enzyme-product specificity by introducing an appropriate aptamer. This then provides a sensing-expression construct, whereby the presence of an enzyme product in the cell triggers self-splicing of the intron sequence to restore the reading frame of the reporter gene and as such to drive expression of the gene product. The sensing construct expresses a protein which marks the cell or permits its growth or survival in or on an otherwise selective media. In this way, introduction or the presence of such product sensing-reporter constructs in cells can be harnessed to provide a multi-parallel rapid screening of cells or libraries for desirable enzyme variants.
