Nitric oxide (NO) is an important signaling molecule that is involved in a wide range of
physiological and pathological events in biology. Metal coordination chemistry, especially …

Bacteria encounter reactive oxygen species (ROS) as a consequence of the aerobic life or
as an oxidative burst of activated neutrophils during infections. In addition, bacteria are …

In high-load anaerobic digestion such as in kitchen waste, side-stream micro-aeration (SMA)
shows excellent operational performance to direct micro-aeration (DMA). It immediately …

Clostridia comprise bacteria of environmental, biotechnological and medical interest and
many commensals of the gut microbiota. Because of their strictly anaerobic lifestyle, oxygen …

Obligate anaerobes are periodically exposed to oxygen, and it has been conjectured that on
such occasions their low‐potential biochemistry will predispose them to rapid ROS …

The unique active site of flavo-diiron proteins (FDPs) consists of a nonheme diiron-
carboxylate site proximal to a flavin mononucleotide (FMN) cofactor. FDPs serve as the …

Microbial anaerobes are exposed in the natural environment and in their hosts, even if
transiently, to fluctuating concentrations of oxygen and its derived reactive species, which …

Flavodiiron proteins (FDPs) catalyze reductive scavenging of dioxygen and nitric oxide in air-
sensitive microorganisms. FDPs contain a distinctive non-heme diiron/flavin mononucleotide …

Flavodiiron proteins have emerged in the last two decades as a newly discovered family of
oxygen and/or nitric oxide reductases widespread in the three life domains, and present in …

Rex, a transcriptional repressor that modulates its DNA-binding activity in response to
NADH/NAD+ ratio, has recently been found to play a role in the solventogenic shift of …
