three-dimensional structure of a truncated active GH68 inulosucrase InuJ of Lactobacillus johnsonii strain NCC533, comprising residues 145-708, in its apo form, with a bound substrate sucrose, and with a transfructosylation product 1-kestose, overview. Particular residues from the nonconserved 1B-1C loop determine product linkage type specificity in GH68 fructansucrases. Residues 210-662 of InuJ constitute the globular catalytic core domain, adopting the five-bladed beta-propeller fold typical of GH68 enzymes. Domain and active site structure analysis, overview |
