Methylates adenine

The DNA adenine methylation status on specific 5¢-GANTC-3¢ sites and its change during the establishment of plant–microbe interactions was demonstrated in several species ofa-proteobacteria. Restriction landmark genome scanning (RLGS), which is a high-resolution two dimensional DNA electrophoresis method, was used to monitor the genomewide change in methylation.

Genomic sequences ofHelicobacter pyloristrains 26695, J99, HPAGI and G27 have revealed an abundance of restriction and modification genes. hp0050, which encodes an N 6 adenine DNA methyltransferase, was cloned, overexpressed and purified to near homogeneity.
