A nomenclature for restriction enzymes, DNA methyltransferases, homing endonucleases and their genes.
A nomenclature is described for restriction endonucleases, DNA methyltransferases, homing endonucleases and related genes and gene products. It provides explicit categories for the many differentExpand

Roles of DNA adenine methylation in host-pathogen interactions: mismatch repair, transcriptional regulation, and more.
The DNA adenine methyltransferase (Dam methylase) of Gammaproteobacteria and the cell cycle-regulated methyltransferase (CcrM) methylase of Alphaproteobacteria catalyze an identical reactionExpand

The dam and dcm strains of Escherichia coli--a review.
The construction of a variety of strains deficient in the methylation of adenine and cytosine residues in DNA by the methyltransferases (MTases) Dam and Dcm has allowed the study of the role of theseExpand

Escherichia coli mutator genes.
The isolation and characterization of Escherichia coli mutator genes have led to a better understanding of DNA replication fidelity mechanisms and to the discovery of important DNA repair pathwaysExpand

Dam methylation: coordinating cellular processes.
GATC sequences in Escherichia coli DNA are methylated at the adenine residue by DNA adenine methyltransferase (DamMT). These methylated residues and/or the level of DamMT can influence cellularExpand

The β Sliding Clamp Binds to Multiple Sites within MutL and MutS*
The MutL and MutS proteins are the central components of the DNA repair machinery that corrects mismatches generated by DNA polymerases during synthesis. We find that MutL interacts directly with theExpand

Hda-mediated inactivation of the DnaA protein and dnaA gene autoregulation act in concert to ensure homeostatic maintenance of the Escherichia coli chromosome.
Initiation of DNA replication in Eschericia coli requires the ATP-bound form of the DnaA protein. The conversion of DnaA-ATP to DnaA-ADP is facilitated by a complex of DnaA, Hda (homologous to DnaA),Expand

Mismatch correction at O6-methylguanine residues in E. coli DNA
Escherichia coli has a correction system which removes mismatched bases from DNA1. Mutants (dam) which lack the major DNA adenine methylase2 are hypersensitive to the effects of base analogueExpand
