Ammonia oxidising archaea are among the most abundant living organisms on Earth and
key microbial players in the global nitrogen cycle. They carry out oxidation of ammonia to …

Heavy metal (loid) s exert selective pressure on microbial communities and evolution of
metal resistance determinants. Despite increasing knowledge concerning the impact of …

Soil represents the largest reservoir of Archaea on Earth. Present-day archaeal diversity in
soils globally is dominated by members of the class Nitrososphaeria. The evolutionary …

Ammonia oxidation, as the first step of nitrification, constitutes a critical process in the global
nitrogen cycle. However, fundamental knowledge of its key enzyme, the copper-dependent …

Ammonia-oxidising archaea (AOA) are a ubiquitous component of microbial communities
and dominate the first stage of nitrification in some soils. While we are beginning to …

Copper membrane monooxygenases (CuMMOs) play critical roles in the global carbon and
nitrogen cycles. Organisms harboring these enzymes perform the first, and rate limiting, step …

The ammonia monooxygenase (AMO) is a key enzyme in ammonia‐oxidizing archaea,
which are abundant and ubiquitous in soil environments. The AMO belongs to the copper …

Ammonia oxidation by archaea and bacteria (AOA and AOB), is the first step of nitrification in
the oceans. As AOA have an ammonium affinity 200-fold higher than AOB isolates, the …

Interactions between metals and microbes are critical in geomicrobiology and vital in
microbial ecophysiological processes. Methane-oxidizing bacteria (MOB) and ammonia …

Ammonia oxidizing archaea (AOA) are among the most abundant microorganisms on earth
and are known to be a major source of nitrous oxide (N2O) emissions, although biochemical …
