PFK — Solanum tuberosum

Summary

PGSC0003DMG400016208, designated PFK (also known as StPFK or PFK5) on potato chromosome 11, encodes a 6-phosphofructokinase (EC 2.7.1.11) with ATP-binding and metal-binding properties, belonging to the phosphofructokinase domain family. This enzyme is associated with glycolytic process, sucrose and starch anabolism, carbohydrate metabolism, response to glucose, and NO storage, and localises to the cytosol and cytoplasm. The gene is linked to fructose 6-phosphate metabolism, glycolytic metabolite concentration, and glycolytic pathway regulation. Related genes in other species connect the family to plant growth and development traits, including root morphology, leaf size, and hexose content, as well as reduced root length under conditions of diminished PFK activity.
