PCMD: Plant comparative metabolome database

Welcome to PCMD !

Plant comparative metabolome database (PCMD) is a comprehensive multi-level comparison database encompassing intra- and cross-species metabolic profiling in 530 plants. The predicted metabolites provided in PCMD are mainly based on the Genome Scale Metabolism Model (GEM), which has been proven to be effective in predicting the presence of metabolites in organisms based on the genome (Mendoza, Olivier, Molenaar,&Teusink, 2019). PCMD contains 213,264 metabolites, 8,384 enzymes, 8,678 reactions, 30,669 experimentally-supported metabolites, 33,397 literature references. Moreover, PCMD also provides a range of user-friendly online tools, such as Species-comparison, Metabolites-enrichment, and ID conversion. The Species-comparison tool allows users to compare the specificity and commonness of metabolites between two different groups of plants at multiple taxonomic levels. The Metabolites-enrichment tool enables users to analyze the enrichment of metabolites. The ID conversion tool allows for efficient conversion of metabolite IDs across multiple published metabolomics databases.
