Semi-rational design and molecular dynamics simulations study of the thermostability enhancement of cellobiose 2-epimerases. [PDF]
Directed evolution using random mutation in vast sequence space leads to the low probability of obtaining target proteins. Emerging engineering strategies with computational tools are developed for more trustable outcomes. We used some semi-rational design methods to modify an industrial enzyme, namely cellobiose 2-epimerase (CE). A mutant was selected

Semi-rational design of nitroarene dioxygenase for catalytic ability toward 2,4-dichloronitrobenzene. [PDF]
ABSTRACT Rieske non-heme dioxygenase family enzymes play an important role in the aerobic biodegradation of nitroaromatic pollutants, but no active dioxygenases are available in nature for initial reactions in the degradation of many refractory pollutants like 2,4-dichloronitrobenzene (24DCNB).

Enhancing the imidase activity of BpIH toward 3-isobutyl glutarimide via semi-rational design. [PDF]
(R)-3-Isobutylglutarate monoamide (R-IBM) is a key intermediate in the synthesis of the analgesic drug pregabalin. Recently, the imidase BpIH derived from Burkholderia phytofirmans was identified as a promising catalyst for the industrial production of R-IBM. Notably, this catalyst has the distinct advantage of achieving a 100% theoretical yield from 3-

Enhancing the Catalytic Activity of Type II L-Asparaginase from Bacillus licheniformis through Semi-Rational Design. [PDF]
Low catalytic activity is a key factor limiting the widespread application of type II L-asparaginase (ASNase) in the food and pharmaceutical industries. In this study, smart libraries were constructed by semi-rational design to improve the catalytic activity of type II ASNase from Bacillus licheniformis.

Development of thermostable sucrose phosphorylase by semi-rational design for efficient biosynthesis of alpha-D-glucosylglycerol. [PDF]
Abstract Sucrose phosphorylase (SPase) can specifically catalyze transglycosylation reactions and can be used to enzymatically synthesize α-D-glycosides. However, the low thermostability of SPase has been a bottleneck for its industrial application. In this study, a SPase gene from Leuconostoc mesenteroides ATCC 12,291 (

Beyond directed evolution—semi-rational protein engineering and design [PDF]
Over the past two decades, directed evolution has transformed the field of protein engineering. The advances in understanding protein structure and function, in no insignificant part a result of directed evolution studies, are increasingly empowering scientists and engineers to device more effective methods for manipulating and tailoring biocatalysts ...
