How to convert between UniRef50 to EC/enzyme number?

Question

[O.rka]

I have a bunch of UniRef90 and UniRef50 identifiers. Is there a table somewhere that has mappings between UniRef and enzyme numbers?

I’m mostly looking for a table that has identifier mappings instead of an R package that uses REST or similar.

For example: https://www.uniprot.org/uniref/UniRef50_P45148

And EC 4.2. 1.1

Please provide examples when asking about any identifiers.

I added a placeholder example but I’ll find a better one to update.

You can use the cluster representatives (P45148 in your case) which represent UniProtKB entries. Upload your list of UniProtKB IDs to the Batch Retrieval / IDmapping at https://www.uniprot.org/id-mapping and map from UniProtKB to UniProtKB. Once you have your results, you can customize the layout of your table by clicking on "Customize colums". Use this interface to add a column for EC numbers (and potentially remove columns you are not interested in). Then you can download your results in tab-separated format (among other formats).
