A simple system is presented for the microscale, direct voltammetry of redox proteins,
typically 25 μg, in the absence of mediators and/or modifiers. The sample consists of a …

Sulfate-reducing bacteria play major roles in the global carbon and sulfur cycles, but it
remains unclear how reducing sulfate yields energy. To determine the genetic basis of …

The electrochemistry of 4, 4'-bipyridine (BiPy) at a Ag electrode and the normal Raman (NR),
resonance Raman (RR), surface-enhanced Raman scattering (SERS), and surface …

Biomacromolecules play a key role in basic life processes. The complexity of their structures
and properties has up to now been a bar to a theoretical treatment of their adsorption onto …

Following the discovery of the tetraheme cythocrome c 3 in the strict anaerobic sulfate-
reducing bacteria (Postgate, JR (1954) Biochem. J. 59, xi; Ishimoto et al.(1954) Bull. Chem …

Voltammetric studies of c-type cytochromes at clay-modified pyrolytic graphite electrodes
have been undertaken as providing a good model for investigating interactions of proteins …

C-type cytochromes are classified into two main groups: i) cytochromes which give fast
electrochemical responses at the conventional eletrodes in the absence of any promoter (eg …

Cyclic voltammetry was used to investigate the kinetics of the electron transfer between
various soluble or solid metal oxides, and polyheme c-type cytochromes from …

An electrochemical study of the periplasmic cytochrome c553 of Desulfovibrio vulgaris
(Hildenborough) is presented. The dependence of the midpoint potential on temperature …

Membrane electrodes (ME) were constructed using gold, glassy carbon and pyrolytic
graphite supports and a dialysis membrane, and used to study the electrochemical behavior …
