PubMed Abstract: Nucleoid associated proteins (NAPs) are essential for chromosome condensation in bacterial cells. Despite being a diverse group, NAPs share two common traits: they are small, oligomeric proteins and their oligomeric state is critical for DNA condensation. Streptomyces coelicolor IHF (sIHF) is an actinobacterial-specific nucleoid-associated protein that despite its name, shares neither sequence nor structural homology with the well-characterized Escherichia coli IHF. Like E. coli IHF, sIHF is needed for efficient nucleoid condensation, morphological development and antibiotic production in S. coelicolor.
