A Flow Cytometry-Based Ultrahigh-Throughput Screening Method for Directed Evolution of Oxidases.

Oxidases are of interest to chemical and pharmaceutical industries because they catalyze highly selective oxidations. However, oxidases found in nature often need to be re-engineered for synthetic applications. Herein, we developed a versatile and robust flow cytometry-based screening platform "FlOxi" for directed oxidase evolution.

Fe(III)-complex mediated bacterial cell surface immobilization of eGFP and enzymes.

We report a facile and reversible method to immobilize a broad range of His6-tagged proteins on the E. coli cell surface through Fe(iii)-metal complexes. A His6-tagged eGFP and four His6-tagged enzymes were successfully immobilized on the cell surface.

Engineering for Efficient Biosynthesis of Fatty Alcohols Based on Enhanced Supply of Free Fatty Acids.

In recent years, production of fatty acid derivatives has attracted much attention because of their wide range of applications in renewable oleochemicals. Microorganisms such as provided an ideal cell factory for such chemical synthesis. In this study, an efficient strategy for the synthesis of fatty alcohols based on enhanced supply of free fatty acids (FFAs) was constructed.

Biochemical characterization of a novel tyrosine phenol-lyase from Fusobacterium nucleatum for highly efficient biosynthesis of l-DOPA.

Tyrosine phenol-lyase (TPL) catalyzes the reversible cleavage of l-tyrosine to phenol, pyruvate and ammonia. When pyrocatechol is substituted for phenol, l-dihydroxyphenylalanine (l-DOPA) is produced. The TPL-catalyzed route was regarded as the most economic process for l-DOPA production.
