The chain of nucleosomes is then wrapped into a 30 nm spiral called a solenoid, where additional H1 histone proteins are associated with each nucleosome to maintain the chromosome structure.

This change in chromatin structure provides a new layer ... proteins might well play a part in modulating histone acetylation, the proteins involved in the DNA methyl-mediated control of histone ...

With this strategy, he discovered over 400 bacterial proteins that contain a signature 3D histone structure called a histone fold, suggesting histones could be scattered across many bacterial species.

They have been known to influence genetic expression by, for example, providing structure ... similar to a gene known to ...
