Please fill out this form to submit the parameters for the generation of a random sequence.

Size of the sequence (20 to 9999 amino acids):

Composition of the sequence:
Equal composition for all amino acids
Composition of a specific sequence - please enter a UniProtKB ID or AC:
Average amino acid composition (computed from UniProtKB/Swiss-Prot)
User specified composition in percent (example: 6.30):

    Ala:  Arg:  Asn:  Asp: 
Cys: Gln: Glu: Gly:
His: Ile: Leu: Lys:
Met: Phe: Pro: Ser:
Thr: Trp: Tyr: Val:
Output format:
