PFK — Solanum tuberosum

Summary

StPFK (PGSC0003DMG400019734) on potato chromosome 4 encodes a phosphofructokinase with 6-phosphofructokinase and diphosphate-fructose-6-phosphate 1-phosphotransferase activities (EC 2.7.1.11), binding ATP and metal ions. The protein localises to the cytosol and cytoplasm. It is associated with glycolytic process, fructose 6-phosphate metabolism, sucrose and starch anabolism, carbohydrate metabolism, response to glucose, and nitric oxide storage. Studies of related genes in other species link the phosphofructokinase family to hexose content, fruit colour, and leaf size.
