<p>This is the Sucrose-6-phosphate phosphohydrolase (S6PP or SPP) C-terminal domain [<cite idref="PUB00010220"/>] as found in plant sucrose phosphatases. These enzymes irreversibly catalyse the last step in sucrose synthesis following the formation of Sucrose-6-Phosphate via sucrose-phosphate synthase (SPS). </p>
