Angelarchaeales Thermoplasmata CuMMO Soil and Sediment Community

Community ID CommunityMech:000234
Ecological State STABLE
Environment grassland and hillslope soils and aquifer sediments
ENVO:00005750

A soil and aquifer-sediment microbial community in which a newly defined Thermoplasmatota archaeal order, Ca. Angelarchaeales, encodes divergent copper membrane monooxygenases (CuMMOs). Twenty genomes from distinct archaeal species were recovered from grassland and hillslope soils and aquifer sediments. The CuMMO proteins resemble Nitrososphaerales (ammonia monooxygenase) enzymes more than bacterial CuMMOs and retain all functional residues required for monooxygenase activity. Angelarchaeales genomes are enriched in blue copper proteins (BCPs) including plastocyanin-like electron carriers and divergent nitrite reductase-like (nirK) 2-domain cupredoxin proteins, encode strong peptide and amino-acid uptake/degradation capacity, and share electron transport mechanisms with Nitrososphaerales. Angelarchaeales are abundant in some of the source environments.
