Type or Paste a Protein Sequence
Type in the field provided to manually enter a sequence, paste a raw sequence (amino acids + stop codons only), or paste the text of a formatted sequence (Fasta, GenPept/UniProt or GCG format).
Enter a name for the new sequence, then click OK.
A new unsaved protein sequence will be created.
