2.3.1.28 | A138S |
site-directed mutagenesis, the enzyme mutant shows increased thermostability at 60-65°C for 24 h compared to the wild-type enzyme, thermostability enhancement results from the A138T replacement and can attributed to both the presence of a hydroxyl group and the bulk of the threonine side chain. CAT A138S mutation confers chloramphenicol resistance to Geobacillus kaustophilus cells at high temperature more efficiently than the wild-type enzyme |

2.3.1.28 | A138T |
site-directed mutagenesis, the enzyme mutant shows increased thermostability at 60-65°C for 24 h compared to the wild-type enzyme, thermostability enhancement results from the A138T replacement and can attributed to both the presence of a hydroxyl group and the bulk of the threonine side chain. CAT A138T mutation confers chloramphenicol resistance to Geobacillus kaustophilus cells at high temperature more efficiently than the wild-type enzyme. The A138T substitution has no effect on CAT activity |

2.3.1.28 | A138V |
site-directed mutagenesis, the enzyme mutant shows highly increased thermostability at 60-65°C for 24 h compared to the wild-type enzyme, thermostability enhancement results from the A138T replacement and can attributed to both the presence of a hydroxyl group and the bulk of the threonine side chain. CAT A138V mutation confers chloramphenicol resistance to Geobacillus kaustophilus cells at high temperature more efficiently than the wild-type enzyme |
