Crystal structure of the adenine-specific DNA methyltransferase M.TaqI complexed with the cofactor analog AETA and a 10 bp DNA containing 5-methylpyrimidin-2(1H)-one at the target base partner positionCrystal structure of the adenine-specific DNA methyltransferase M.TaqI complexed with the cofactor analog AETA and a 10 bp DNA containing 5-methylpyrimidin-2(1H)-one at the target base partner position
Structural highlights
FunctionMTTA_THEAQ This methylase recognizes the double-stranded sequence TCGA, causes specific methylation on A-4 on both strands and protects the DNA from cleavage by the TaqI endonuclease. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. See Also |
