Protein
Putative type I restriction enzyme specificity protein MPN_638
Organism
Mycoplasma pneumoniae (strain ATCC 29342 / M129)
Function
The M and S subunits together form a methyltransferase (MTase) that methylates two adenine residues in complementary strands of a bipartite DNA recognition sequence. Subunit S dictates DNA sequences specificity (By similarity).
Similarity
Belongs to the type-I restriction system S methylase family.
