General Information

EC Number General Information Comment Organism
2.4.1.14 metabolism the enzyme SPS is encoded by different gene families. SPS exists in multiple forms which show differential distributions and functional specializations in the plant tissues. SPS activity is highly regulated by hierarchy of mechanisms including transcriptional control Solanum tuberosum
2.4.1.14 additional information most of the potato cultivars are autotetraploid (2n = 4x = 48), highly heterozygous, and show high level of DNA polymorphism in its genome. Natural allelic variations are also common in potato genes Solanum tuberosum
2.4.1.14 physiological function sucrose-phosphate synthase refers to a key enzyme in sucrose biosynthesis in both photosynthetic and nonphotosynthetic tissues of plants Solanum tuberosum
