  • FUNCTION Sucrose-cleaving enzyme that provides UDP-glucose and fructose for various metabolic pathways (By similarity). Functions in developing seeds by supplying substrates for the biosynthesis of storage products (PubMed:11910009).CATALYTIC ACTIVITY an NDP-alpha-D-glucose + D-fructose = a ribonucleoside 5'-diphosphate + sucrose + H(+)ACTIVITY REGULATION Activated by phosphorylation at Ser-10 by CPK23.SUBUNIT Homotetramer or heterotetramer with SUS1.TISSUE SPECIFICITY Predominantly expressed in the leaf tissues. Expressed in seeds, and at lower levels in roots. Expressed in leaf mesophyll and phloem (at protein level).DEVELOPMENTAL STAGE Expressed early in seed development with a peak at 6 days after pollination (DAP) and then decreases slightly (at protein level). In the caryopse, slightly expressed during the pre-storage phase and was strongly expressed from the early to middle storage phase.INDUCTION By anaerobic stress. Up-regulated by sucrose, fructose and glucose and by sugar starvation. By submergence.PTM Phosphorylated at Ser-10 by CPK23 in developing seeds.SIMILARITY Belongs to the glycosyltransferase 1 family. Plant sucrose synthase subfamily.
