Table 1A (supplemental data). Summary of nano-LC-ESI-MS/MS data from the CN-PAGE gel (Figure 2A) gel of stroma of A. thaliana chloroplasts. Complementary MALDI-TOF MS data are not listed. The spots were picked in the Clp complex from low to high molecular mass.Z is the charge state of the measured precursor ion.MH+ is thecalculated mass of the protonated precursor ion. Only sequence tags matching to Clp proteins are listed.
