Abstract EN
Bacterial nucleoid-associated proteins (NAPs) form nucleoprotein complexes and influence the expression of genes.
Recent studies have shown that some plasmids carry genes encoding NAP homologs, which play important roles in transcriptional regulation networks between plasmids and host chromosomes.
In this study, we determined the distributions of the well-known NAPs Fis, H-NS, HU, IHF, and Lrp and the newly found NAPs MvaT and NdpA among the whole-sequenced 1382 plasmids found in Gram-negative bacteria.
Comparisons between NAP distributions and plasmid features (size, G+C content, and putative transferability) were also performed.
We found that larger plasmids frequently have NAP gene homologs.
Plasmids with H-NS gene homologs had less G+C content.
It should be noted that plasmids with the NAP gene homolog also carried the relaxase gene involved in the conjugative transfer of plasmids more frequently than did those without the NAP gene homolog, implying that plasmid-encoded NAP homologs positively contribute to transmissible plasmids.
