methyl-based methanogenesis

traitmech:000192 · CLASS · PROPOSED

A methanogenesis in which methylated compounds donate methyl groups that are transferred to coenzyme M and reduced to methane.

DOI:10.1128/mmbr.00024-22
Methyl-based methanogenesis is one of three broad categories of archaeal anaerobic methanogenesis, including both the methyl dismutation (methylotrophic) pathway and the methyl-reducing (also known as hydrogen-dependent methylotrophic) pathway

Bueno de Mesquita et al. define methyl-based methanogenesis as the methanogenesis branch covering methyl dismutation and hydrogen-dependent methyl-reducing pathways.
DOI:10.3389/fmicb.2017.01198
acetoclastic methanogenesis using acetate, and methylotrophic methanogenesis using methylated compounds, such as methanol, methylamines

Evans et al. describe methylotrophic methanogenesis as the methylated-compound-using branch among major methanogenic carbon-source pathways.

Not yet attached to a section of this record — a curator sets attaches_to (e.g. causal_graphs#some_edge) so the gap shows beside the mechanism it concerns.

The pinned METPO snapshot contains only obsolete METPO:1000866 Methylotrophic methanogenesis. The existing methylotrophic record is the broader reduced-one-carbon trophic type, and GO:0015948 methane biosynthetic process is exact only for the broader methanogenesis parent, so no exact active external class has yet been resolved for this methyl-substrate branch.

Minted methyl-based methanogenesis as a DOI-backed child of methanogenesis after a repository-wide duplicate review covering ignored and hidden files; the pinned METPO snapshot has only an obsolete Methylotrophic methanogenesis class.
