On subspaces of H¹ isomorphic to H¹

Reassociation of histone H1 to H1-depleted polynucleosomes.

A new procedure is described for the reassociation of histone H1 to rat liver polynucleosomes selectively depleted of H1 and nonhistone proteins. The fidelity of reconstitution was scrutinized by nuclease digestion and sedimentation studies monitoring the regeneration of structural features which disappear following removal of H1. The results demonstrate that the 166-base pair barrier of digest...

Binding of phosphorylated histone H1 to DNA.

A chromatin associated protein kinase was used to add 3 moles of phosphate to seryl side chains of 1 mole of histone H1. The DNA binding properties of this in vitro phosphorylated H1 were compared with those of unmodified H1. Considerably more radioactive superhelical DNA was retained on nitrocellulose filters at 20mM-40mM NaCl by phosphorylated H1 than by unmodified H1. However, zone velocity ...

H1 antihistamines and driving

Driving performances depend on cognitive, psychomotor and perception functions. The CNS adverse effects of some H1 antihistamines can alter the patient ability to drive. Data from studies using standardized objective cognitive and psychomotor tests (Choice Reaction Time, Critical Flicker Fusion. Digital Symbol Substitution Test), functional brain imaging (Positron Emission Tomography, functiona...
