Abstract:

Microbial electrosynthesis is an emerging green technology that explores the capability of a particular group of microorganisms to drive their metabolism toward the production of hydrogen or value-added chemicals from electrons supplied by electrode surfaces. The cytochrome PccH showed the largest increase in transcription when electrons are supplied to Geobacter sulfurreducens biofilms. Gene knock-out experiments have shown that the electron transfer toward G. sulfurreducens cells was completely inhibited by the deletion of the gene encoding for cytochrome PccH. This identifies a crucial role for this protein in G. sulfurreducens microbial electrosynthesis mechanisms, which are currently unknown. In this work, we present the backbone (1H, 13C and 15N) and heme assignment for PccH in the oxidized state. The data obtained paves the way to identify and structurally map the molecular interaction regions between the cytochrome PccH and its physiological redox partners.
