Methanogenesis from methylamines

Methanogenesis from methylamines (Reaction 6, Table 2) follows almost the same route as methanol to CH4 and CO2 [227], although each system probably requires specific components for substrate transport, and to form a common methylated product. For example, extracts of M. barkeri grown on trimethylamine (TMA) produce methane from TMA + H2, but extracts from methanol- or dimethylamine-grown cells do not [227],...

In contrast to Sec-tRNA and fMet-tRNA formation, Pyl-tRNA y formation can occur by direct acylation of pyrrolysine onto tRNA i Pyrrolysine (Pyl), the twenty-second amino acid, was discovered incorporated in methylamine methyltrans-ferases from Methanosarcinaceae, a branch of methanogenic archaea that has the ability to reduce a wide variety of compounds to methane including carbon dioxide, acetate, methanol, methylated thiols, and methylated amines (72). Methanogenesis... 

In marine sediments below the sulfate zone, methanogenesis is the predominant terminal pathway of organic carbon degradation. Methane may also be formed from acetate or from organic Cj-compounds such as methanol or methylamines ...
