List of identified phosphoproteins.

Phosphorylated proteins, peptides and residues (phosphosites) identified by mass spectrometry in protein extracts from young Arabidopsis seedlings after rubisco depletion, IMAC enrichment and 2-DE separation of phosphoproteins. (a) pS, pT and pY = phosphorylated serine, threonine and tyrosine residues; M* = oxidized methionine. (b) Protein reported in the PhosPhAt 4.0 database. 30,31 (c) Peptide reported in the PhoPhAt 4.0 database with a different protein phosphorylation site. 30 31 (d) Protein previously reported in Arabidopsis seedlings. 23 (e) Peptide reported in the PhosPhAt 4.0 database with the same protein phosphorylation site. 30, 31 (f) Peptide previously reported in Arabidopsis seedlings with a different protein phosphorylation site. 23 (g) Peptide previously reported in Arabidopsis seedlings with the same protein phosphorylation site. 23 List of identified phosphoproteins.
