MtrB - LvT

Level T expression construct containing MtrB under control of Ptrc10 constitutive Synechocystis sp. And E. coli promoter and TrrnB double terminator.

Metal-reducing microorganisms such as Shewanella oneidensis MR-1 and Geobacter metallireducens have evolved an innate EET pathway that makes them ideal for bioelectricity applications. The most characterised EET pathway in S. oneidensis MR-1 includes MtrCAB complex. Based on the current understanding, the electrons extracted from the oxidation of a substrate are ultimately transferred to the periplasmic decaheme cytochrome MtrA during anaerobic respiration. Subsequent electron transfer to the outer membrane β-barrel protein MtrB places MtrA in direct contact with MtrC. MtrC is re-oxidised by reducing terminal electron acceptors, such as electrodes, via direct or mediated electron transfer.
