Succinylation is the important type of PTM that plays a key role in regulating the main function of all aspects of cell metabolism in both eukaryotes and prokaryotes, such as improving the thermal stability of various proteins, which modifications involved in a variety of diseases, including cardia, hepatic and some pulmonary diseases. In order to improve the understanding of Succinylation information, we have provided a collection of Succinylation databases and will be modified with time.
