英文名 methylamine-corrinoid protein Co-methyltransferase
Example Structure Example Structure of methylamine-corrinoid protein Co-methyltransferase EC#: 2.1.1.248
别名 corrinoid-dependent methylamine methyltransferase, MMA methyltransferase, MMA:CoM methyltransferase, MMA:MMCP methyltransferase, MMAMT, monomethylamine methyltransferase, monomethylamine:coenzyme M methyl transferase, monomethylamine:MMCP methyltransferase, MtmB, mtmB1, mtmB2
EC Number 2.1.1.248
CAS编号
Comments The enzyme, which catalyses the transfer of a methyl group from methylamine to a methylamine-specific corrinoid protein (MtmC), is involved in methanogenesis from methylamine. The enzyme contains the unusual amino acid pyrrolysine [3]. Methylation of the corrinoid protein requires the central cobalt to be in the Co(I) state. During methylation the cobalt is oxidized to the Co(III) state. The methylated corrinoid protein is substrate for EC 2.1.1.247, methylated methylamine-specific corrinoid protein:coenzyme M methyltransferase.
Cofactor
History
Reactions Methylamine + a [Co(I) methylamine-specific corrinoid protein] = a [methyl-Co(III) methylamine-specific corrinoid protein] + ammonia.
