Activated acetic acid by carbon fixation on (Fe,Ni)S under primordial conditions.
In experiments modeling the reactions of the reductive acetyl-coenzyme A pathway at hydrothermal temperatures, it was found that an aqueous slurry of coprecipitated NiS and FeS converted CO and CH3SHExpand

Primordial reductive amination revisited
Amino acids are formed efficiently by reductive amination of α-keto acids under aqueous, conditions with freshly precipitated FeS or Fe(OH)2 and with NH3, CH3NH2 or (CH3)2NH at pH values near theirExpand

Peptides by activation of amino acids with CO on (Ni,Fe)S surfaces: implications for the origin of life.
In experiments modeling volcanic or hydrothermal settings amino acids were converted into their peptides by use of coprecipitated (Ni,Fe)S and CO in conjunction with H2S (or CH3SH) as a catalyst andExpand

Lipid transfer from plants to arbuscular mycorrhiza fungi
Arbuscular mycorrhiza (AM) symbioses contribute to global carbon cycles as plant hosts divert up to 20% of photosynthate to the obligate biotrophic fungi. Previous studies suggested carbohydrates asExpand

Laticifer-Specific cis-Prenyltransferase Silencing Affects the Rubber, Triterpene, and Inulin Content of Taraxacum brevicorniculatum12[C][W]
Certain Taraxacum species, such as Taraxacum koksaghyz and Taraxacum brevicorniculatum, produce large amounts of high-quality natural rubber in their latex, the milky cytoplasm of specialized cellsExpand

Histone H2A C-Terminus Regulates Chromatin Dynamics, Remodeling, and Histone H1 Binding
The tails of histone proteins are central players for all chromatin-mediated processes. Whereas the N-terminal histone tails have been studied extensively, little is known about the function of theExpand

A Possible Primordial Peptide Cycle
α-Amino acids can undergo peptide formation by activation with carbon monoxide (CO) under hot aqueous conditions in the presence of freshly coprecipitated colloidal (Fe,Ni)S. We now show thatExpand

A rubber transferase activator is necessary for natural rubber biosynthesis in dandelion
High-molecular-mass natural rubber is a valuable plant-derived poly(cis-1,4-isoprene) with many industrial and medical applications. It is synthesized by a rubber cis-prenyltransferase (CPT) complexExpand

Pterin cofactor, substrate specificity, and observations on the kinetics of the reversible tungsten-containing aldehyde oxidoreductase fromClostridium thermoaceticum
The αβ subunits of the tungsten-containing reversible aldehyde oxidoreductase ofClostridium thermoaceticum were shown to contain a pterin cofactor in the form of a mononucleotide. The substrateExpand

A transferable plasticity region in Campylobacter coli allows isolates of an otherwise non‐glycolytic food‐borne pathogen to catabolize glucose
Thermophilic Campylobacter species colonize the intestine of agricultural and domestic animals commensally but cause severe gastroenteritis in humans. In contrast to other enteropathogenic bacteria,Expand
