The present invention relates to a single-chain monellin-like protein which is stable and which is at least 100-fold sweet as compared to sucrose on the weight basis. The present invention also relates to a nucleic acid encoding said monellin-like protein. Preferably, the nucleic acid further comprises a promoter and a signal sequence for directing expression and secretion of the encoded monellin-like protein in the methylothrophic yeast Pichia pastoris. The present invention further relates to a recombinant Pichia pastoris cell containing the nucleic acid encoding the monellin-like protein, a process for producing the monellin-like protein from the recombinant Pichia pastoris and product of the process.
