'''DNA-BINDING PROTEIN HU FROM BACILLUS STEAROTHERMOPHILUS'''<br />


==Overview==
==DNA-BINDING PROTEIN HU FROM BACILLUS STEAROTHERMOPHILUS==
The prokaryotic protein HU, integration host factor (IHF) from Escherichia, coli, and transcription factor 1 (TF1) from bacteriophage SPO1 are closely, related molecules. Biochemical results suggest that the role of these, proteins is to bind and bend DNA. From the high-resolution structure of, HU, we propose a model for this interaction with DNA. Crucial amino acid, differences between the proteins can be rationalized in terms of their, different specific functions.
