Biochemistry
A notable trait of Methanosarcinaceae is that they are methanogens that incorporate the unusual amino acid pyrrolysine into their enzymes.[9] The enzyme monomethylamine methyltransferase catalyzes the reaction of monomethylamine to methane. This enzyme includes pyrrolysine. The unusual amino acid is inserted using a unique tRNA, the anticodon of which is UAG. In most organisms, and in most Methanosarcinaceae proteins, UAG is a stop codon. However in this enzyme, and anywhere else pyrrolysine is incorporated, likely through contextual markers on the mRNA, the pyrrolysine-loaded tRNA is inserted instead of the release factor. They also have a unique aminoacyl-tRNA synthetase to specifically load this tRNA with pyrrolysine. This unique adaptation is still the subject of significant study.
