2.4.1.390 D991N besides native (alpha1->4) and (alpha1->3) linkages,the mutant shows 10% (alpha1->6) linkage increases compared to 1% for wild-type in products. The orientation of acceptor binding in the mutant is favorable for (alpha1->6) linkage synthesis -, 777891 2.4.1.390 G1028R besides native (alpha1->4) and (alpha1->3) linkages,the mutant shows 8% (alpha1->6) linkage increases compared to 1% for wild-type in products. The orientation of acceptor binding in the mutant is favorable for (alpha1->6) linkage synthesis -, 777891 2.4.1.390 E1405D the mutant displays lower total activity and lower hydrolytic activity and slightly decreased transglucosylase efficiency 777891 2.4.1.390 T1400E the mutant has relatively higher total activity but is more hydrolytic than the wild-type enzyme -, 777891 2.4.1.390 D991H the mutant has relatively higher total activity but is more hydrolytic than the wild-type enzyme. The mutant enzyme has increased temperature optimum of 45°C -, 777891 2.4.1.390 A1398Y the mutant shows decreased total activity and slightly increased hydrolytic activity, leading to low transglucosylase efficiency -, 777891 2.4.1.390 G1028R the mutant shows decreased total activity and slightly increased hydrolytic activity, leading to low transglucosylase efficiency. The mutant enzyme has increased temperature optimum of 45°C 777891
