Protein

Alpha-1,4-glucan:maltose-1-phosphate maltosyltransferase

Gene

glgE

Organism
Corynebacterium efficiens (strain DSM 44549 / YS-314 / AJ 12310 / JCM 11189 / NBRC 100395)
Status
Unreviewed-Annotation score: -Protein inferred from homologyi

Functioni

Maltosyltransferase that uses maltose 1-phosphate (M1P) as the sugar donor to elongate linear or branched alpha-(1->4)-glucans. Is involved in a branched alpha-glucan biosynthetic pathway from trehalose, together with TreS, Mak and GlgB.UniRule annotation

Catalytic activityi

Alpha-maltose 1-phosphate + ((1->4)-alpha-D-glucosyl)(n) = phosphate + ((1->4)-alpha-D-glucosyl)(n+2).UniRule annotation
