| Description | C-5 cytosine-specific DNA methylases (C5 Mtase) are enzymes that specifically methylate the C-5 carbon of cytosines in DNA [ , , ]. Such enzymes are found in the proteins described below.As a component of type II restriction-modification systems in prokaryotes and some bacteriophages. Such enzymes recognise a specific DNA sequence where they methylate a cytosine. In doing so, they protect DNA from cleavage by type II restriction enzymes that recognise the same sequence. The sequences of a large number of type II C-5 Mtases are known. In vertebrates, there are a number of C-5 Mtases that methylate CpG dinucleotides. The sequence of the mammalian enzyme is known. C-5 Mtases share a number of short conserved regions. This conserved region contains a conserved Pro-Cys dipeptide in which the cysteine has been shown to be involved in the catalytic mechanism; it appears to form a covalent intermediate with the C6 position of cytosine [ ]. |
