Novel aspects of iron sulfur cluster biosynthesis in sulfate reducing bacteria (768.17)

Iron-sulfur cluster biosynthesis.

Iron-sulfur (Fe-S) clusters are present in more than 200 different types of enzymes or proteins and constitute one of the most ancient, ubiquitous and structurally diverse classes of biological prosthetic groups. Hence the process of Fe-S cluster biosynthesis is essential to almost all forms of life and is remarkably conserved in prokaryotic and eukaryotic organisms. Three distinct types of Fe-...

Feedback regulation of iron-sulfur cluster biosynthesis.

I clusters ([Fe-S] clusters) represent one of nature’s simplest, functionally versatile, and perhaps most ancient prosthetic groups (1). Among the familiar types of [Fe-S] clusters are [2Fe2S] and [4Fe-4S] clusters, which usually are attached to their protein partners by four cysteine thiol ligands (Fig. 1). Proteins that contain one or more [Fe-S] clusters are commonly called [Fe-S] proteins, ...

Simultaneous Electricity Generation and Sulfur Removal by Electrogenic Sulfate Reducing Bacteria in BES System

The modern BioElectrochemical technologies can convert the energy stored in the chemical bonds of biodegradable organic materials to renewable electrical energy through the catalytic reactions of microorganisms while treating the waste waters. The present research was conducted to evaluate the efficiency of a single-chamber Bioelectrochemical system with the carbon aerogel catalyst, as a simple...
