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
