2.4.1.13 additional information L-sorbose, 5-keto-D-fructose, D-tagatose, fructose 6-phosphate, levanbiose can replace fructose to a small extent, no glucosyl acceptors are D-xylulose, L-rhamnulose, D-glucoheptulose, D-mannoheptulose, turanose, inulobiose, melibiulose, lactulose, cellobiulose, 3,4-di-O-methylfructose, dihydroxyacetone, pyruvate Beta vulgaris ? - ? 89 2.4.1.13 additional information it is possible that sucrose synthase provides monosaccharide precursors for mucilage synthesis Zea mays ? - ? 89 2.4.1.13 additional information it is supposed that the sucrose synthase activity in sugar-beet roots is controlled by sucrose synthesized in leaves rather than by phytohormones Beta vulgaris ? - ? 89 2.4.1.13 additional information mtSUS plays a non-sucrolytic role Zea mays ? - ? 89 2.4.1.13 additional information sucrose synthase appears to be largely responsible for feeding assimilated carbon into sink metabolism Vicia faba ? - ? 89 2.4.1.13 additional information sucrose synthase appears to be largely responsible for feeding assimilated carbon into sink metabolism Daucus carota ? - ? 89 2.4.1.13 additional information sucrose synthase appears to be largely responsible for feeding assimilated carbon into sink metabolism. SH1 isozyme preferentially provides the substrate for cellulose biosynthesis, whereas SUS1 generates precursors for starch biosynthesis Zea mays ? - ? 89 2.4.1.13 additional information SUS2 may function to regulate SUS1 membrane association by formation of SUS1–SUS2 hetero-oligomers Zea mays ? - ? 89 2.4.1.13 additional information nitrogen fixation can occur in Lotus japonicus nodules even in the absence of LjSUS3 (the major nodule-induced isoform of SUS), so LjSUS1 must also contribute to the maintenance of nitrogen assimilation Lotus japonicus ? - ? 89 2.4.1.13 additional information results support the model that nodule-enhanced Suc synthase 1 of the model legume Medicago truncatula is required for the establishment and maintenance of an efficient N-fixing symbiosis Medicago truncatula ? - ? 89
