I have a file of 25600 peptide sequences:
>sp YYRITYGETGGNSPVQEFTVPGSK >sp YYTEFPTVLDITAEDPSK >sp YYTGVVNNNEMVALQR >sp YYTLNGSK >sp YYTSASGDEMVSLK >sp YYTYLIMNK >sp YYVTIIDAPGHR >sp
I used EMBOSS Backtranseq to convert the peptide into DNA sequences, but it will only take 500 peptide sequences. Is there any way on R or Python where I can run a script that will convert the peptide sequences into DNA sequences please?
I new to this area of bioinformatics, so any help would be greatly appreciated.
