Abstract
Disclosed herein are sweet proteins that are variants of Brazzein, and nucleotide sequences capable of expressing them. Through a replacement of an amino acid in the naturally occurring Brazzein sequence with Arg or Ala (or the addition of Arg or Ala), the taste profile and sweetness strength can be changed.
