A proteomic analysis of potential substrates for SynPTP, observed from substrate trapping experiment, in soluble fractions of Synechocycistis sp. PCC 6803 cell extracts.

Protein ID	No. of peptides matched/total	Predicted Mr	Observed Mr
Phycocyanin β	5/13	18.8	19
Phycocyanin α	3/13	17.8	17

Predicted molecular mass (Mr) was deduced from amino acid sequence, calculated by using the PROTEIN CALCULATOR v3.2 program (http://www.scripps.edu/∼cdputnam/protcalc.html). Observed molecular mass was determined from Coomassie blue stained SDS gel.
