TL;DR: The data suggest that OMV have functions in predation and possibly in transfer of intercellular signaling molecules between cells, and suggest novel functions for these transporters.

TL;DR: Evidence is presented that in the autotrophic methanogen the four 2-oxoacid oxidoreductases have anabolic functions, Vor and Ior being involved in the biosynthesis of amino acids from fatty acids taken up from the growth medium, as shown by 14C-labelling studies.

TL;DR: Results indicate that MbHdrD harbors the active site of heterodisulfide reduction and that a flavin is not involved in catalysis.

TL;DR: Findings suggest that HdrA harbors the site of heterodisulfide reduction and that the catalytic mechanism of the enzyme is similar to that of pyridine-nucleotide-dependent thioredoxin reductase.

TL;DR: The primary structures of the four subunits Fwd ABCD of the tungsten enzyme from Methanobacterium thermoautotrophicum which were determined by cloning and sequencing the encoding genes fwdABCD were found to contain sequence motifs characteristic for molybdopterin-dinucleotide-containing enzymes indicating that this subunit harbors the active site.
