We are only beginning to understand the breadth of enzyme diversity in the archaeal world. Here's an example of how an archaeon can deploy a phospholipase to kill certain bacteria...

Implications for #PaleoSky
It’s clear that methanogen diversity and methane emissions from the GSL have been severely understudied and underestimated and that emissions will only worsen during lake drying. We hope to soon change that! Our research was funded by the NASA Exobiology (to Tim McDermott) and DOE BER (me) programs.
Hydroxylated isoprenoidal glycerol dialkyl glycerol tetraethers (OH-isoGDGTs) are used as sea surface temperature (SST) proxies through the RI-OH and …

Archaea the hornets of the microbial world. Discuss.
www.biorxiv.org/content/10.6...
TLDR: Archaeon kills bacterium with secreted phospholipase. Pretty nifty way to kill bacteria if you are a microbe with a very different lipid make-up, I reckon. No need to worry about accidentally killing yourself.
To prepare for DNA replication, a short region of DNA base-pairs must be broken, termed melting, allowing a helicase to gain a foothold on an isolated DNA strand. Here, authors use single-particle cry...
Abstract. Ammonia-oxidizing archaea (AOA) have repeatedly been detected with molecular methods on human skin, yet their persistence, physiological traits,
Archaea kill bacteria, at least on occasion. The molecular underpinnings of these lethal interactions are barely understood. Here, we describe cinquedea, an α/β hydrolase secreted by the halophilic ar...

New paper out in Microbiology Spectrum: “Proteomic stress response by a novel methanogen enriched from the Great Salt Lake”, first author William Christian. We enriched a novel, euryarchaeotal, methyl-dismutating methanogen that grows at 16% salinity. 🦠 #microsky journals.asm.org/doi/full/10....
We named this archaeon in honor of Maurice Hilleman (1919-2005), a microbiologist and vaccinologist who graduated from Montana State University. Over the course of his career, he developed over 40 vaccines, including 8 that are recommended for children in the USA. His vaccines
