Functional studies of the small subunit of EcoHK31I DNA methyltransferase
{{output}}
EcoHK31I DNA methyltransferase recognizes the sequence 5'-YGGCCR-3' and adds a methyl group to the fifth position of the internal cytosine to protect the DNA from cleavage by its cognate endonuclease. M.EcoHK31I is composed of polypeptides alpha and beta. Poly... ...
