Novel m4C modification in type I restriction-modification systems
We identify a new subgroup of Type I Restriction-Modification enzymes that modify cytosine in one DNA strand and adenine in the opposite strand for host protection. Recognition specificity has been determined for ten systems using SMRT sequencing and each recognizes a novel DNA sequence motif. Previously characterized Type I systems use two identical copies of a single methyltransferase (MTase)...
متن کاملDiversity within the Campylobacter jejuni type I restriction-modification loci.
The type I restriction-modification (hsd) systems of 73 Campylobacter jejuni strains were characterized according to their DNA and amino acid sequences, and/or gene organization. A number of new genes were identified which are not present in the sequenced strain NCTC 11168. The closely related organism Helicobacter pylori has three type I systems; however, no evidence was found that C. jejuni s...
متن کاملDNA target recognition domains in the Type I restriction and modification systems of Staphylococcus aureus
Staphylococcus aureus displays a clonal population structure in which horizontal gene transfer between different lineages is extremely rare. This is due, in part, to the presence of a Type I DNA restriction-modification (RM) system given the generic name of Sau1, which maintains different patterns of methylation on specific target sequences on the genomes of different lineages. We have determin...
متن کاملDistribution of Type I Restriction–Modification Systems in Streptococcus suis: An Outlook
Streptococcus suis is a porcine commensal and pathogen with zoonotic potential. We recently identified a novel Type I restriction-modification (R-M) system in a zoonotic S. suis clone which has emerged in the Netherlands. Here, we describe the DNA inversions in the specificity subunit of this system in S. suis serotype 2, clonal complex 20 and explain the absence of domain movement by the absen...
متن کاملDNA restriction-modification systems mediate plasmid maintenance.
Two plasmid-carried restriction-modification (R-M) systems, EcoRI (from pMB1 of Escherichia coli) and Bsp6I (from pXH13 of Bacillus sp. strain RFL6), enhance plasmid segregational stability in E. coli and Bacillus subtilis, respectively. Inactivation of the endonuclease or the presence of the methylase in trans abolish the stabilizing activity of the R-M systems. We propose that R-M systems med...
