one of these fragments yielded amino acid sequence information spanning fifteen residues , which was identified as probably belonging to human methyltransferase by virtue of both its significant sequence homology to three procaryote forms of o6-mt encoded by the ada , ogt ( both from e. coli ) and dat ( b. subtilis ) genes , and sequence position of the radiolabelled methyl group which matched the position of the conserved procaryote methyl acceptor site cysteine residue .
