Protein

Sucrose synthase 3

Gene

SUS3

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Sucrose-cleaving enzyme that provides UDP-glucose and fructose for various metabolic pathways. Modulates metabolic homeostasis and direct carbon towards starch synthesis in developing seeds.1 Publication

Catalytic activityi

NDP-glucose + D-fructose = NDP + sucrose.

Kineticsi

  1. KM=41.96 mM for D-fructose (synthetic reaction) at pH 9.42 Publications
  2. KM=0.2 mM for UDP-glucose (synthetic reaction) at pH 9.42 Publications
  3. KM=108.2 mM for sucrose (degradative reaction) at pH 62 Publications
  4. KM=48 mM for sucrose (degradative reaction) at pH 72 Publications
  5. KM=0.09 mM for UDP (degradative reaction) at pH 62 Publications
  6. KM=0.25 mM for UDP (degradative reaction) at pH 72 Publications
  7. KM=0.15 mM for ADP (degradative reaction) at pH 72 Publications

Vmax=7.32 µmol/min/mg enzyme for synthetic reaction at pH 9.42 Publications

Vmax=3.03 µmol/min/mg enzyme for degradative reaction at pH 62 Publications

Vmax=950 µmol/min/mg enzyme for degradative reaction at pH 72 Publications

pH dependencei

Optimum pH is 6.0-7.0 for degradative reaction and 7.0 (PubMed:22184213) or 9.0-9.5 (PubMed:17257168) for synthetic reaction.2 Publications
