Computer‐Based Design to Improve Bacillus thuringiensis Chitinase for Industrial Applications

ChemistryOpen, Volume 15, Issue 4, April 2026.
Hotspot‐guided mutagenesis identifies Gly291 as a key catalytic determinant in Bacillus thuringiensis chitinase. Substitution with alanine improves substrate accommodation and lowers the activation barrier by ∼47%, reducing it from 94.66 to 49.83 kcal/mol. Structural integrity is retained while catalytic efficiency is enhanced, demonstrating a rational
