5-Deazaflavin cofactors enhance the metabolic flexibility of microorganisms by catalyzing a
wide range of challenging enzymatic redox reactions. While structurally similar to riboflavin, 5…

Advances in imaging technologies have revealed that many bacteria possess organelles
with a proteomically defined lumen and a macromolecular boundary. Some are bound by a …

The atmosphere has recently been recognized as a major source of energy sustaining life.
Diverse aerobic bacteria oxidize the three most abundant reduced trace gases in the …

Recent physiological and ecological studies have challenged the long-held belief that microbial
metabolism of molecular hydrogen (H 2 ) is a niche process. To gain a broader insight …

H 2 metabolism is proposed to be the most ancient and diverse mechanism of energy-conservation.
The metalloenzymes mediating this metabolism, hydrogenases, are encoded by …

… subunit gene as follows: 95 C for 5 min; 30 cycles of denaturing at 95 C for 30 s, annealing
at 55 C for 30 s and extension at 72 C for 30 s; and a final extension of 72 C for 5 min. Owing …

Background Gastrointestinal tract (GIT) microbiomes in ruminants play major roles in host
health and thus animal production. However, we lack an integrated understanding of microbial …

… at high cell-specific rates to subatmospheric levels at 10 C but not −20 C; derived power
was of the same magnitude as H 2 oxidation at 10 C (average 4.6 fW cell −1 ), suggesting …

Farmed ruminants are the largest source of anthropogenic methane emissions globally. The
methanogenic archaea responsible for these emissions use molecular hydrogen (H 2 ), …

… The resultant vol and particles were aligned to C 2 symmetry axis to exploit the C 2 symmetry
within the HucS 2 L 2 . The symmetry aligned particles were then refined with C 2 symmetry …
