2.4.1.214 additional information structural analysis of the FT of Helicobacter pylori by systematic C-terminal truncation reveals that up to 80 residues, including the region rich in hydrophobic and positively charged residues (434-478) and 5 of the 10 tandem repeats of 7 amino acids each (399-433) can be removed without significant change in structure and catalysis, half of the heptad repeats required to maintain both the secondary and native quaternary structures, systematic deletion of the C-terminus considerably improves the solubility of the protein, truncated forms are highly specific for type 2 sugar substrates that contain the Galbeta-1,4-GlcNAc structure, type 1 substrate Galbeta-1,3-GlcNAc is not accepted Helicobacter pylori
