Isolation of molecular markers from specific chromosomal intervals using DNA pools from existing mapping populations.

abstract：:DNA cytosine-5 methyltransferases (C5-MTases) are valuable models to study sequence-specific modification of DNA and are becoming increasingly important tools for biotechnology. Here we describe a structure-guided rational protein design combined with random mutagenesis and selection to change the specificity of the H...
