Mapping Uniprot IDs
BioMart is a very handy tool when you want to map between different databases. The following is a list of IDs from the UniProtKB/Swiss-Prot database of Arabidopsis thaliana proteins that are supposedly involved in flavonoid metabolism:
P42813, Q9LS08, Q9ZST4, Q9SYM2, P51102, Q9LPV9, Q9FE25, Q96323, Q9FKW3, P13114, P41088, Q9S818, Q96330, O22203, Q39224, O22264, Q9SD85, Q9LYT3, Q9FJA2, Q43128, P43254, O04153, Q43125, Q9S9P6, Q94C57, Q9LNE6, Q9FK25, Q9SYM5, Q9ZQ95
Generate a list that shows to which Ensembl Gene IDs these UniProtKB/Swiss-Prot IDs map. Also include the gene name and description.
Click the New button on the toolbar. Choose the Plants Mart database. Choose the Arabidopsis thaliana genes dataset.
Click on Filters in the left panel. Expand the GENE section. Select ID list limit – UniProt/Swissprot ID(s). Enter the list of IDs in the text box (either comma separated or as a list).
Click on Attributes in the left panel. Expand the GENE section. Deselect Transcript Stable ID. Select Gene name and Gene description. Expand the EXTERNAL section. Select UniProtKB/SwissProt ID(s).
Click the Results button on the toolbar. Select View All rows as HTML or export all results to a file. Tick the box Unique results only.
Your results should show 29 / 32833 genes.
