Welcome to qPTMplants

Post-translational modification (PTM) is a biochemical process that changes the properties and extends the chemical composition of a protein by participating in the addition of chemical groups (such as phosphate, succinyl and sulfate) to specific amino acid residues or by proteolytic cleavage of the protein sequence backbone. More than 200 PTMs have been registered in UniProt, and they can regulate the structure, function, and localization of proteins. Plant PTMs play critical roles in nearly all biological processes, such as signal transduction, metabolism, stress resistance, plant immunity and other cellular events.

Here, we developed an integrative database of quantitative PTMs in plants named qPTMplants, which curated and hosted the published 23 types of PTMs including 429,821 sites on 123,551 proteins in 43 plant species from 293 literature. Moreover, we collected and organized 620,509 kinds of quantitative events for 136,700 sites on 55,361 proteins from 139 literature.
