Frontiers of carbonate clumped isotope thermometry
Carbonate minerals contain stable isotopes of carbon and oxygen with different masses
whose abundances and bond arrangement are governed by thermodynamics. The clumped …

Methyl (alkyl)-coenzyme M reductases: nickel F-430-containing enzymes involved in anaerobic methane formation and in anaerobic oxidation of methane or of short …
RK Thauer - Biochemistry, 2019 - ACS Publications
Methyl-coenzyme M reductase (MCR) catalyzes the methane-forming step in methanogenic
archaea. The active enzyme harbors the nickel (I) hydrocorphin coenzyme F-430 as a …

Tracing sources of atmospheric methane using clumped isotopes
We apply a recently developed measurement technique for methane (CH4) isotopologues
(isotopic variants of CH4—13CH4, 12CH3D, 13CH3D, and 12CH2D2) to identify …

Well-hidden methanogenesis in deep, organic-rich sediments of Guaymas Basin
Abstract Deep marine sediments (> 1mbsf) harbor~ 26% of microbial biomass and are the
largest reservoir of methane on Earth. Yet, the deep subsurface biosphere and controls on …

H2 and CH4 outgassing rates in the Samail ophiolite, Oman: implications for low-temperature, continental serpentinization rates
Abstract Reduced (H 2-and CH 4-rich) and hyperalkaline fluids are products of subsurface
reactions accompanying serpentinization of ultramafic rocks. H 2 and CH 4 produced during …
