Inventory of Arabidopsis PRMT and PKMTs known or predicted to be targeted to chloroplasts.

Potential protein Lys/Arg methyltransferases found in the Arabidopsis genome were analyzed for their predicted subcellular localization by using SUBA3, AtSubP, and ChloroP 1.1 [44]–[46]. Proteins with a confident prediction for plastid targeting are shown. Data extracted from the predictors are: for SUBA3, consensus localization and number of predictors (out of 18) indicating a plastid targeting; for AtSubP, prediction using the best hybrid-based classifier (AA+PSSM+N-Center-C+PSI-BLAST); for ChloroP 1.1, presence of a predictable chloroplast transit peptide (cTP). Experimental localizations using GFP-tagging or mass spectrometry (MS) have been reported in the indicated references.
