UniProt:Q01401 SBE1

chain
  • transit peptide:1-64
  • chain:65-820
checksum 7DE65880013A7B15
comment
  • FUNCTION Catalyzes the formation of the alpha-1,6-glucosidic linkages in starch by scission of a 1,4-alpha-linked oligosaccharide from growing alpha-1,4-glucan chains and the subsequent attachment of the oligosaccharide to the alpha-1,6 position.CATALYTIC ACTIVITY Transfers a segment of a (1->4)-alpha-D-glucan chain to a primary hydroxy group in a similar glucan chain.PATHWAY Glycan biosynthesis; starch biosynthesis.SUBUNIT Monomer.SUBCELLULAR LOCATION Isoform 2 lacks the putative transit peptide and may be a cytosolic isoform.SIMILARITY Belongs to the glycosyl hydrolase 13 family. GlgB subfamily.
