Redox reactions play important roles in almost all biological processes, including
photosynthesis and respiration, which are two essential energy processes that sustain all life …

Mitochondrial glycerol-3-phosphate dehydrogenase (mGPDH) is not included in the
traditional textbook schemes of the respiratory chain, reflecting the fact that it is a non …

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

Chemolithotrophic bacteria that use sulfate as terminal electron acceptor (sulfate-reducing
bacteria) constitute a unique physiological group of microorganisms that couple anaerobic …

▪ 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 …

O 2 photoreduction by photosynthetic electron transfer, the Mehler reaction [1], was
observed in all groups of oxygenic photosynthetic organisms [2–4], but the electron transport …

Sulfate-reducing bacteria (SRB) are strict anaerobes that are often found in biotopes where
oxic conditions can temporarily exist. The bacteria have developed several defense …

Many enzymes use one or more cofactors, such as biotin, heme, or flavin. These cofactors
may be bound to the enzyme in a noncovalent or covalent manner. Although most …

Desulfovibrio gigas is a strict anaerobe that contains a well-characterized metabolic
pathway that enables it to survive transient contacts with oxygen. The terminal enzyme in …

Pyruvate: ferredoxin oxidoreductase (PFOR) catalyzes the oxidative decarboxylation of
pyruvate to acetyl-CoA and CO 2. The catalytic proficiency of this enzyme for the reverse …
