The "Adding missing entries" tab handles curation of TPs or parent compounds that were not identified by the LeadMine text mining (e.g., "acyclovir diphosphate" in Figure ). In this case, the structure of the compound can be drawn using chemdoodle, which will return the SMILES of the drawn structure. The compound name and SMILES of the compound are then entered as text inputs to save the reaction. Information about the biosystem, enzyme, and transformation type may also be saved as described for the "Transformation reaction curation" tab described above. Further explanation and screenshots are included in the ShinyTPs documentation on the GitLab repository .
