Metal-Dependent Effects and Crowding Robustness of Pseudomonas fluorescens Esterase I. [PDF]

open access: yesChembiochem
Pseudomonas fluorescens esterase I retains catalytic activity in metal‐rich and crowded environments, despite metal‐specific inhibitory effects. These findings highlight its robustness for biocatalytic applications in complex environments. Industrial biocatalysts are strongly influenced by their physicochemical environment, yet systematic studies on ...
