The last years have witnessed a steady increase of social and political awareness for the
need of studying, monitoring, and controlling several anthropological activities that are …

Heme–copper oxidases (HCO), nitric oxide reductases (NOR), and sulfite reductases (SiR)
catalyze the multi-electron and multi-proton reductions of O2, NO, and SO32−, respectively …

TubercuList (http://tuberculist. epfl. ch/), the relational database that presents genome-
derived information about H37Rv, the paradigm strain of Mycobacterium tuberculosis, has …

Multielectron redox reactions often require multicofactor metalloenzymes to facilitate
coupled electron and proton movement, but it is challenging to design artificial enzymes to …

Nitrogen and sulfur are abundant constituents of plant and algal cells that are assimilated at
the lowest oxidation number, as NH 4+ and S 2−, although they can (in the case of sulfur …

Sulfate reduction is one of the earliest types of energy metabolism used by ancestral
organisms to sustain life. Despite extensive studies, many questions remain about the way …

Cysteine dioxygenase is a mononuclear iron-dependent enzyme responsible for the
oxidation of cysteine with molecular oxygen to form cysteine sulfinate. This reaction commits …

Despite its reactivity and hence toxicity to living cells, sulfite is readily converted by various
microorganisms using distinct assimilatory and dissimilatory metabolic routes. In respiratory …

Mononuclear, non-heme-Fe (II) centers are key structures in O2 metabolism and catalyze an
impressive variety of enzymatic reactions. While most are bound via two histidines and a …

Corynebacterium glutamicum, a gram-positive soil bacterium, has been regarded as an
aerobe because its growth by fermentative catabolism or by anaerobic respiration has, to …
