Annotation

Description
The bacterial histone-like proteins HU play an important role in the structure of the bacterial nucleoid. They bind and bend DNA in a sequence-independent manner. HU proteins are required in the assembly of higher order nucleoprotein structures mediating a variety of DNA metabolic events, such as replication, transcription, site-specific recombination and transposition. HU promotes DNA flexibility in a similar way to its closely related proteins: integration host factor (IHF) and transcription factor 1 (TF1) from bacteriophage SPO1.
