Identification of a Campylobacter coli methyltransferase targeting adenines at GATC sites
FEMS Microbiology Letters, 364(7).
MeSH headings : Adenine / metabolism; Animals; Campylobacter coli / enzymology; Campylobacter coli / genetics; Cattle; DNA Methylation; Genome, Bacterial; Humans; Methyltransferases / genetics; Methyltransferases / isolation & purification; Methyltransferases / metabolism; Nucleotide Motifs; Open Reading Frames; Sequence Analysis / methods
TL;DR:
To determine whether ORF0059 mediated MboI resistance and hence encoded a putative N6‐adenine DNA methyltransferase, the gene was cloned immediately upstream of a chloramphenicol resistance cassette (cat) and a PCR fragment harboring ORF 0059‐cat was transformed into C. coli 11601, suggesting a direct role of this gene in methylation of adenines at GATC sites.
