The generation of focused mutant libraries at hotspot residues is an important strategy in directed protein evolution. Existing methods, such as combinatorial active site testing and residual coupling analysis, depend primarily on the evolutionary conserved information to find the hotspot residues. Hardly any attention has been paid to another important(More)
Sporolactobacillus inulinus has attracted scientific and commercial interest due to its high efficiency in d-lactic acid production. Pyruvate kinase (PYK) is one of the key regulatory points in glycolysis, and well-activated PYK can improve d-lactic acid production. A novel Mn2+/Mg2+-dependent PYK from S. inulinus was expressed in Escherichia coli and(More)
Sporolactobacillus inulinus, a homofermentative lactic acid bacterium, is a species capable of efficient industrial d-lactic acid production from glucose. Glucose phosphorylation is the key step of glucose metabolism, and fine-tuned expression of which can improve d-lactic acid production. During growth on high-concentration glucose, a fast induction of(More)
