Proteome-wide discovery of in vivo metacaspase substrates can be obtained by positional proteomics approaches such as N-terminal COFRADIC, for example by comparing the N-terminal proteomes (or N-terminomes) of wild-type plants to transgenic plants not expressing a given metacaspase. In this chapter we describe a protocol for the preparation of plant tissue proteomes, including differential isotopic labelling allowing for a comparison of in vivo N-terminomes that serves as the starting point for N-terminal COFRADIC studies.
