Heterologous expression of Deinococcus geothermalis amylosucrase in Corynebacterium glutamicum for luteolin glucoside production

•Deinococcus geothermalis amylosucrase (DGAS) was expressed in C. glutamicum (cDGAS).•Deinococcus geothermalis amylosucrase (DGAS) was expressed in E. coli (eDGAS).•The optimal temperature of cDGAS was lower than that of eDGAS.•Luteolin transglucosylation activity of cDGAS was higher than that of eDGAS.•β-strand ratios were lower for cDGAS than for eDGAS.
