2.4.1.13	ADP + sucrose	sucrose synthase catalyzes the de novo production of ADPglucose linked to starch biosynthesis in heterotrophic tissues of plants	
2.4.1.13	ADP + sucrose	ADP-glucose produced by SuSy is linked to starch biosynthesis. SuSy exerts a strong control on the starch biosynthetic process and controls the production of ADP-glucose accumulating in source leaves	
2.4.1.13	ADP-glucose + D-fructose	-	
2.4.1.13	additional information	it is possible that sucrose synthase provides monosaccharide precursors for mucilage synthesis	
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	
2.4.1.13	additional information	mtSUS plays a non-sucrolytic role	
2.4.1.13	additional information	sucrose synthase appears to be largely responsible for feeding assimilated carbon into sink metabolism	
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	
2.4.1.13	additional information	SUS2 may function to regulate SUS1 membrane association by formation of SUS1–SUS2 hetero-oligomers	
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	
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	
2.4.1.13	additional information	SuS is involved in the Suc to polysaccharides conversion. Glycogen content in an Anabaena sp. mutant strain with an insertion inactivation of susA was lower than in the wild type strain under diazotrophic conditions, while both glycogen and polysaccharides levels are higher in a mutant strain constitutively overexpressing susA

2.4.1.13	NDP-glucose + D-fructose	-	
2.4.1.13	sucrose + UDP	sucrose loaded into the phloem of a poplar leaf is used directly by sucrose synthase associated with various beta-glucan synthases in the stem for UDPglucose formation in the sink tissue, thereby conserving the high energy bond between glucose and fructose

2.4.1.13	UDP + sucrose	role of isoforms I, II	
2.4.1.13	UDP + sucrose	biochemical pathway for sucrose degradation. Repression of invertase and mobilization of sucrose via the energetically less costly route provided by SuSY is important in growing tubers because it conserves oxygen and allows higher internal oxygen tensions to be maintained	
2.4.1.13	UDP + sucrose	under appropriate conditions, the enzyme participates in the in vitro mobilization of sucrose from tonoplast vesicles	
2.4.1.13	UDP-alpha-D-glucose + D-fructose	-

2.4.1.13	UDP-glucose + D-fructose	-	
2.4.1.13	UDP-glucose + D-fructose	the level of sucrose synthase activity in the developing cotyledons of plant genotypes differing in seed size at 500 to 600 growing degree days is correlated with the final seed size at maturity
