A recently granted patent (Publication Number: US11884923B2) discloses a fructose-4-epimerase variant with specific amino acid substitutions, aimed at enhancing its efficiency in producing tagatose. The variant, with substitutions at key positions such as 52, 136, 197, 317, 320, and 414 from the N-terminus, must have at least 90% sequence identity to the original amino acid sequence (SEQ ID NO: 1) to be considered within the scope of the patent.

The patent also covers compositions and methods for producing tagatose using the aforementioned fructose-4-epimerase variant. The compositions include the variant along with fructose, while the methods involve converting fructose into tagatose by utilizing the variant. By specifying the amino acid substitutions and their positions, the patent aims to provide a more efficient and effective way of producing tagatose, a valuable sweetener with various applications in the food industry.
