What is it about?
Unlike the others, surface charge engineering by modifying crucial surface amino acid residues is an approach of structure-based rational design that may largely ensure the catalytic efficiency while improving thermostabiliy by keeping the flexibility of the catalytic core.

Why is it important?
The optimization of charge-charge interactions has also been proven feasible for thermostability improvement. However, underdeveloped bioinformatic tools previously limited the widespread application of surface charge engineering. We aimed to obtain optimized mutants of BisGlu16B with improved thermostability and retained enzymatic activity through strengthening charge–charge interactions on the basis of ETSS calculation.
