How to get EC-numbers corresponding with the genes in R

[TheBumpper]

Hi

I'm trying to create a R program to find the gene and their EC-number. I got gene names using biomaRt, but could not find a option to get the EC-number.
Does anyone have a suggestion to do this?

Thanks in advance for your help.

mar <- useMart("unimart", "uniprot")
getBM("ec_number", "gene_name", "BRCA1", mar)
