Properties of a Tobacco DNA Methyltransferase, NtMET1 and Its Involvement in Chromatin Movement during Cell Division

Background and Aims Plants possess three types of DNA methyltransferase, among which methyltransferase type 1 (MET1) is considered to play a major role by maintaining the CpG methylation patterns. However, little information is available as to its enzymatic activity, interacting proteins and spatial and temporal behaviours during DNA replication. In the present study, one example, NtMET1 from tobacco plants, was selected and an analysis was made of its biochemical properties and cellular localization.
