Large-Scale Analysis of Protein Crotonylation Reveals Its Diverse Functions in Pinellia ternate

We generated a global crotonylome analysis of the leaves in Pinellia ternata. We found 4509 crotonylated sites on 1757 proteins totally, and three specific amino acids surrounding crotonylation sites were identified in Pinellia ternata: KcrF, K***Y**Kcr and Kcr****R. Gene Ontology (GO) and KEGG pathway enrichment analyses showed that two crucial alkaloid biosynthesis related enzymes and many stress-related proteins were also highly crotonylated. Furthermore, several enzymes participate in the carbohydrate metabolism pathway, were modified also by lysine crotonylation.
