Align protein or nucleotide sequences using ClustalOmega. Accepts FASTA text, UniProt IDs, PDB IDs, or file upload.
Each sequence must begin with a >header line followed by the sequence.
Example: P69905, P68871 — sequences will be fetched from UniProt automatically.
Example: 1HHO, 2HHB — FASTA sequences will be fetched from RCSB PDB.
The file must contain at least 2 sequences in FASTA format.
