2. S-Adenosyl methionine - Wikipedia

   en.wikipedia.org/wiki/S-Adenosyl_methionine

   ATP + L-methionine + H2O phosphate + diphosphate + S-adenosyl-L-methionine. The sulfonium functional group present in S-adenosyl methionine is the center of its peculiar reactivity. Depending on the enzyme, S-adenosyl methionine can be converted into one of three products:

   en.wikipedia.org/wiki/Precorrin-3B_C17-methyl...

   The systematic name of this enzyme class is S-adenosyl-L-methionine:precorrin-3B C17-methyltransferase. Other names in common use include precorrin-3 methyltransferase , and CobJ . This enzyme is part of the biosynthetic pathway to cobalamin (vitamin B 12 ) in aerobic bacteria and during this step the macrocycle ring-contracts so that the ...

7. Phenylethanolamine N-methyltransferase - Wikipedia

   en.wikipedia.org/wiki/Phenylethanolamine_N...

   S-adenosyl-L-methionine (SAM) is a required cofactor. [6] The active site binding region for the cofactor SAM contains a rich number of pi bonds from phenylalanine and tyrosine residues in the active site help to keep it in its binding pocket through pi stacking. Among all known PNMT variants in nature there are 7 crucial aromatic residues ...

8. L-isoaspartyl methyltransferase - Wikipedia

   en.wikipedia.org/wiki/L-isoaspartyl_methyl...

   PIMT acts to transfer methyl groups from S-adenosyl-L-methionine to the alpha side chain carboxyl groups of damaged L-isoaspartyl and D-aspartyl amino acids.The enzyme takes the end methyl residue from the methionine side chain and adds it to the side chain carboxyl group of L-isoaspartate or D-aspartate to create a methyl ester.

9. rRNA (adenine-N6-)-methyltransferase - Wikipedia
