Bifunctional alpha-galactosidase/sucrose kinase AgaSK

UniProtKB accession:  G4T4R7

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Bifunctional enzyme with alpha-galactosidase and sucrose kinase activities. Produces sucrose-6-phosphate directly from raffinose. Binds ATP. Phosphorylates sucrose specifically on the C6 position of glucose in the presence of ATP. Hydrolyzes melibiose, raffinose, stachyose and synthetic substrate p-nitrophenyl-alpha-D-galactopyranoside with high activity. Low activity against locust bean gum, guar gum and synthetic substrates xylose alpha-D-4-nitrophenol, glucose alpha-D-4-nitrophenol and o-nitrophenyl-alpha-D-galactopyranoside.
