3.1.1.79 | V158A | 4fold increase in activity with 4-nitrophenyl caproate, in contrast to wild-type mutant also shows activity against tributyrin. V158A mutant shows an improved thermostabilty compared with wild-type. V158A mutant shows a greater affinity to p-nitrophenyl acetate. Mutant is more sensitive to Cu2+, but less sensitive to Hg2+ compared to wild-type | Streptomyces coelicolor |
3.1.1.79 | V158A/W87F | significantly increased activity with 4-nitrophenyl butyrate in the double mutant, double mutant shows similar affinity to p-nitrophenyl acetate | Streptomyces coelicolor |
3.1.1.79 | W87F | mutation shows no effect on substrate specificity. Mutant is less thermostable compared to wild-type. V158A mutant shows an improved thermostabilty compared with wild-type. W87F mutant shows a lower affinity to p-nitrophenyl acetate compared to wild-type. Mutant is more sensitive to Cu2+ and Hg2+ compared to wild-type | Streptomyces coelicolor |
