PKC — Solanum tuberosum

Summary

PGSC0003DMG400025298 (PKC) on potato chromosome 4 encodes a pyruvate kinase (EC 2.7.1.40). The product contains pyruvate kinase domains and binds ATP, potassium and magnesium ions. In potato, PKC is associated with pyruvate metabolism, carbohydrate and sucrose anabolism and breakdown, fructose uptake, cell wall polysaccharide anabolism, and the oxidative pentose pathway. It is linked to responses to abiotic stimuli and has been connected to starch concentration, sugar and glucose content, potassium content, net photosynthetic rate and drought tolerance. The protein localises to the chloroplast stroma, cytosol and cytoplasm. Related genes in other species link the family to plastidial pyruvate kinase function.
