Lysine methyltransferase (aKMT) is responsible for catalyzing the methylation of lysine residues in target proteins, using S-adenosyl-L-methionine (SAM) as a methyl donor. The enzyme exhibits broad substrate specificity, showing methylation primarily at "Lys-11", "Lys-16" and "Lys-31" of the vault chromatin protein Cren7 as well as several recombinant Sulfolobus proteins in vitro Ability. aKMT Protein, Sulfolobus islandicus is the recombinant aKMT protein, expressed by E. coli , with tag free.
