I have a list of several protein names, their primary gene name and their amino acid sequence (as extracted from the 'SEQRES' section in their corresponding PDB files).
I'm looking for the genomic position (triad of translated nucleotides) of a specific amino acid in the sequence (i.e. residue number 64 in a protein sequence of 344 amino acids).
Is it possible to BLAT an amino acid sequence by using biomaRt in R? Do you suggest other methods to achieve this task?
