Synthesis of Fructooligosaccharides by IslA4, a truncated inulosucrase from Leuconostoc citreum

Abstract

Domain truncation together with the selection of the appropriate reaction conditions resulted in the synthesis of various FOS, which were produced as the main transferase products of inulosucrase (IslA4). These results therefore demonstrate that bacterial fructosyltransferase could be used for the synthesis of inulin-type FOS.
