ID 2.1.1.384 DE [methyl-Co(III) methoxylated-aromatic-compound-specific corrinoid DE protein]--tetrahydromethanopterin methyltransferase. CA 5,6,7,8-tetrahydromethanopterin + methyl-Co(III)-[methoxylated-aromatic- CA compound-specific corrinoid protein] = 5-methyl-5,6,7,8- CA tetrahydromethanopterin + Co(I)-[methoxylated-aromatic-compound-specific CA corrinoid protein] + H(+). CC -!- The enzyme has been characterized from several archaeal species. CC -!- In the methanogenic archaeon Methermicoccus shengliensis the enzyme CC participates in methanogenesis from methoxylated aromatic compounds, CC while in the non-methanogenic Archaeoglobus fulgidus it participates CC in methoxydotrophic growth. CC -!- The enzyme catalyzes the transfer of a methyl group bound to the CC cobalt cofactor of a dedicated corrinoid protein (MtoC) to CC tetrahydromethanopterin or tetrahydrosarcinapterin. cf. EC 2.1.1.385. //
