Nishida Y, Ikeya T, Mikawa T, Inoue J, Ito Y, Shintani Y, et al.
Biochem Biophys Rep . 2017 Sep; 8:318-324. PMID: 28955971
In prokaryotic cells, genomic DNA forms an aggregated structure with various nucleoid-associated proteins (NAPs). The functions of genomic DNA are cooperatively modulated by NAPs, of which HU is considered to...
