PLMD (Protein Lysine Modifications Database) is an online data resource specifically designed for protein lysine modifications (PLMs). The PLMD 3.0 database was extended and adapted from CPLA 1.0 (Compendium of Protein Lysine Acetylation) database and CPLM 2.0 (Compendium of Protein Lysine Modifications) database
CPLA is covered by Thomson Reuters Data Citation Index.
A description of the CPLA 1.0 database is available at http://nar.oxfordjournals.org/content/39/suppl_1/D1029.full
