Post-translational modifications and databases


DAPPLE 2 allows you to identify PTM sites using data for 19 different post-translational modifications (PTMs) from 16 different online databases. The PTMs you have to choose from, along with the databases from which the data are derived, are listed below. Also indicated is the number of PTM sites from each database. To visit the website for a particular database, click on the name of that database.
