Method for analyzing methylation of a genome
First Claim
1. A method for analyzing methylation of a genome, comprising:
- (a) cleaving a sample comprising DNA from the genome using an MspJI-family member to obtain DNA fragments that comprise a modified cytosine at a defined position that is within 30 nucleotides from either end of the fragments; and
(b) obtaining sequence from either ends of the fragments produced in (a) to determine the defined position of the modified cytosine in the DNA fragments.

Abstract
Compositions, methods and related uses are provided relating to cleaving modified DNA. For example, a set of DNA fragments obtainable by enzymatic cleavage of a large DNA is described where at least 50% are similarly sized and have a centrally positioned modified nucleotide. In addition, an enzyme preparation is provided that includes one or more enzymes that recognize a modified nucleotide in a DNA and cleave the DNA at a site that is at a non-random distance from the modified nucleotide. The one or more enzymes are further characterized by an N-terminal conserved domain with greater than 90% amino acid sequence homology to WXD(X)10YXGD. The related uses include creating a methylome, methods of purifying DNA fragments containing a modified nucleotide and diagnostic applications.
