Copyright OpenHelix. No use or reproduction without express written consent10 SMART Sequence or ID Searches start with a sequence or ID
Copyright OpenHelix. No use or reproduction without express written consent11 Start with a Sequence Known proteins or predictions IDs A known protein or prediction as amino acid sequence Run the search Supplement the default search Use batch access for multiple sequences Here, you must start with an ID. Do not use a gene name or symbol. Look up the ID in UniProt, for example Or, you can begin with a protein sequence
