to the wild-type enzyme RgDAAO, leading to a mutant Zn7 with greater than 2000-fold improvement in specific activity toward the unnatural substrate D-glufosinate, which was converted into PPO, a precursor of an excellent herbicide, L-PPT. Computational analysis revealed that the higher activity was mainly caused by an extended reaction pocket with greater hydrophilicity.
The marine environment is a rich source of antimicrobial compounds with promising pharmaceutical and biotechnological applications. The Pseudoalteromonas genus harbors one of the highest proportions of bacterial species producing antimicrobial molecules. For decades, the presence of proteins with L-amino acid oxidase (LAAO) and antimicrobialactivity in Pseudoalteromonas luteoviolacea has been known
