;THE A-RIBOSWITCH SEQUENCE WAS DERIVED FROM THE
SEQUENCE LOCATED UPSTREAM OF THE ADD GENE ENCODING
FOR THE ADENINE DEAMINASE FROM VIBRIO VULNIFICUS.
THE STRUCTURE CONTAINED IN THIS ENTRY IS A 
COMPLEX BETWEEN ADENINE AND A DOMAIN ('APTAMER
DOMAIN') OF THE RIBOSWITCH, WHICH STIMULATES
TRANSLATION OF THE ADD GENE IN RESPONSE TO THE
PRESENCE OF ADENINE IN THE CELL.
THE SEQUENCE CAN BE FOUND NATURALLY AND IT MATCHES
THE GENEBANK ENTRY 27358288 AE016809 OF VIBRIO
VULNIFICUS (RESIDUES 202511-202580).
