Bacterial chromosome organization and segregation - PMC

WebThe organization of bacterial chromosomes is profoundly influenced by DNA-binding proteins, and in particular by a heterogeneous class of abundant proteins called nucleoid-associated proteins (NAPs) (Fig. 5.4 ). NAPs typically bind relatively nonspecifically across bacterial genomes, wrapping, bending, or bridging DNA. WebApr 1, 2010 · Abstract. In bacterial genomes composed of more than one chromosome, one replicon is typically larger, harbors more essential genes than the others, and is considered primary. The greater variability of secondary chromosomes among related taxa has led to the theory that they serve as an accessory genome for specific niches or …
