SPP2 — Cucumis melo

Summary

MELO3C012320.2 (SPP2) on melon chromosome 11 encodes a sucrose-phosphate phosphatase, an enzyme with sucrose-phosphate phosphatase activity that requires magnesium binding. The protein contains a sucrose-phosphatase domain and belongs to the HAD-superfamily hydrolase. This gene is associated with sucrose biosynthesis, carbohydrate metabolism, and phloem transport, and is linked to the biological processes of sucrose anabolism and methylation. It is also associated with nuclear localisation. Studies of related genes in other species link the SPP family to sucrose-phosphate phosphatase activity (EC 3.1.3.24). The gene is related to SPP1.
