A nucleotide insertion between two adjacent methyltransferases in Helicobacter pylori results in a bifunctional DNA methyltransferase.

The Biochemical journal - 1 Feb 2011

Kumar Ritesh, Rao Desirazu N

Abstract excerpt

Helicobacter pylori has a dynamic R-M (restriction-modification) system. It is capable of acquiring new R-M systems from the environment in the form of DNA released from other bacteria or other H. pylori strains. Random mutations in R-M genes can result in non-functional R-M systems or R-M systems with new properties. hpyAVIAM and hpyAVIBM are two solitary DNA MTase (methyltransferase) genes adjacent to each...
