PhD 3.9 | Engineering and oriented immobilization of enzymes on electrodes
Description of project:
Enzymes will be engineered by fusion with metal-binding peptides or protein binding modules to immobilize them on electrode materials (e.g. platinum, gold, carbon). For this purpose, metal-binding peptides are screened by phage display and naturally occurring protein binding modules are engineered. Candidate peptides and proteins will be tagged to the bioelectrocatalysts for oriented immobilization and the reactions electrochemically investigated.
Background:
Enzymes as bioelectrocatalysts need to be connected to an electrode. Chemical immobilization methods lead to random orientations of the enzyme on the electrode and deactivation. The oriented immobilization of enzymes in a monolayer can be achieved by peptide or protein sequences/modules that bring the enzymes in productive contact with the electrode.
Research Objectives:
• In silico and in vitro screening of peptides and protein binding to electrode materials
• Protein modelling and engineering for fusion proteins, production of fusion proteins
• Biochemical characterization and electrochemical testing
Methods:
• Affinity screening (fluorescence microscopy, SPR)
• Phage display screening of metal-binding peptides using model metal surfaces
• Protein engineering (Rational design) of protein binding modules
• Recombinant protein expression and purification
• Biochemical and electrochemical characterization
