First Comprehensive Proteome Analyses of Lysine Succinylation in Physalis angulata, a medicinal plant with a high pharmaceutical value

Physalis angulata is a medicinal plant with a high pharmaceutical value that is widely cultivated in East Asia. Lysine succinylation, a newly identified post-translational modification, is associated with various cellular processes. However, the regulatory mechanism underlying the metabolism of P. angulata is largely unknown. Here, liquid chromatography tandem-mass spectrometry combined with a high-efficiency succinyl-lysine antibody was used to identify the succinylated peptides in P. angulata. In total, 422 lysine succinylation sites in 242 proteins were identified.
