The defining trait of obligate anaerobes is that oxygen blocks their growth, yet the underlying
mechanisms are unclear. A popular hypothesis was that these microorganisms failed to …

Dissimilatory sulphate reduction is the unifying and defining trait of sulphate-reducing
prokaryotes (SRP). In their predominant habitats, sulphate-rich marine sediments, SRP have …

Electrons can tunnel through proteins in microseconds with a modest release of free energy
over distances in the 15 to 20 Å range. To span greater distances, or to move faster, multiple …

Sulfate reducing bacteria (SRB) have existed throughout much of Earth's history and remain
major contributors to carbon cycling in modern systems. Despite their importance …

In photosynthesis, linear electron transport from water to nicotinamide adenine dinucleotide
phosphate (NADP+) cannot satisfy the ATP/NADPH production stoichiometry required by the …

▪ Abstract Throughout the first 90 years after their discovery, sulfate-reducing bacteria were
thought to be strict anaerobes. During the last 15 years, however, it has turned out that they …

Recently, the zinc metallo-hydrolase family of the β-lactamase fold has grown quite rapidly,
accompanied by the accumulation of sequence and structure data. The variety of the …

Since nickel was first discovered in hydrogenase in 1981 [83] many reviews on various
aspects of nickel hydrogenases have appeared [34, 64, 78, 94,125,150,154 …

Background The role of bacterial symbionts that populate octocorals (Cnidaria, Octocorallia)
is still poorly understood. To shed light on their metabolic capacities, we examined 66 high …

Geobacter sulfurreducens, previously classified as a strict anaerobe, tolerated exposure to
atmospheric oxygen for at least 24 h and grew with oxygen as the sole electron acceptor at …
