BioSpectroElectrochemistry of natural and artificial metaloproteins

Parycja Kielb and her team aim at exploring how nature performs complicated redox reactions constituting key processes in the environment and life, like biomass  degradation and or cellular respiration. At the heart of such processes  are often redox biocatalytic metalloproteins which present the main  inspiration for our mechanistic investigations. The research team wants to understand how they can harness and further engineer the unrivaled efficiency of such natural biological systems towards the development of artificial biohybrid systems applicable in bioelectronic devices.

Methodologically, they employ the combination of experimental techniques including advanced Raman spectroscopy, electrochemistry, and protein engineering. Specifically, surface-enhanced resonance Raman spectro-electrochemistry allows them to correlate the structural information of the molecule interfaced on electrodes with its redox functionality.

CV

Patrycja Kielb studied Molecular Biophysics at Jagiellonian University, Krakow, Poland which she completed with a Master Degree in 2012. Before finishing her Master’s, she performed various reserach internships: (i) at the Insittute of Catalysis and Physical Chemistry of Interfaces, Polish Academy of Sciences, Krakow, Poland and (ii) at Institute of Chemistry and Biology in Lisbon, Portugal as an Erasmus Scholar. After these research experiences, she became passionate about exploring the mechanistic details of catalytic reactions in natural systems. She continued to investigate these topics as a PhD Scholar of Excellence Cluster of Unifying Concepts in Catalysis (UniCat) at TU Berlin under supervision of Prof. Dr. Inez Weidinger and Prof. Dr. Peter Hildebrandt (Biophysical Chemistry). In this time, she explored redox properties and structure-function relationship of various heme-containing bio- and molecular catalysts which she defended in 2017 with summa cum laude. After her PhD, she joined the group of Prof. Harry B. Gray (Bioinorganic Chemistry) as a postdoc where she investigated the role of protein matrix in supporting redox reactions in metalloprotiens on the example of Cu-containing enzyme. In 2020, she returned to Germany for her 2nd postdoc at University of Potsdam with JProf. D. Henrike Müller-Werkmeister (Physical Chemistry). Shortly after that, in 2021 she started her independent group at the University of Bonn.
