Trehalase (EC 3.2.1.28) hydrolyzes only α, α'- trehalose and is present in a variety of organisms, but is most important in insects and fungi. Crystallographic data showed that bacterial trehalase has D312 and E496 as the catalytical residues and three Arg residues in the active site. Those residues have homologous in all family 37 trehalases including Spodoptera frugiperda trehalase (D322, E520, R169, R227, R287). To test the role of these residues, mutants of trehalase were produced. All… CONTINUE READING
