PMID: 10732672
We found that Drosophila embryo extract contains a protein activity (or activities) that can destabilize nucleosomes, resulting in increased sensitivity to DNase I, release of nucleosomal supercoiling, high levels of...

FEBS Lett
. 1999 Jul;
452(3):215-8.
PMID: 10386593
DNA within chromatin has considerably more restricted flexibility in comparison with naked DNA. This raises the main question of how the functioning multi-enzyme complexes overcome the nucleosomal level of DNA...

J Biomol Struct Dyn
. 1999 May;
16(5):1097-106.
PMID: 10333179
We evaluated the contribution of in vivo histone acetylation to the folding of chromatin into its higher-order structures. We have compared high-order folding patterns of hyperacetylated vs. unmodified chromatin in...

Krajewski W, Becker P
Proc Natl Acad Sci U S A
. 1998 Mar;
95(4):1540-5.
PMID: 9465051
Increased acetylation at specific N-terminal lysines of core histones is a hallmark of active chromatin in vivo, yet the structural consequences of acetylation leading to increased gene activity are only...

J Biomol Struct Dyn
. 1997 Apr;
14(5):641-9.
PMID: 9130085
We have used the intercalative agent ethidium bromide to examine the association between chromatin high-order folding and the twist of internucleosomal DNA regions. The analysis was carried out on intact...

Mol Gen Genet
. 1996 Sep;
252(3):249-54.
PMID: 8842144
In view of the wide chromosomal distribution of short alternating purine-pyrimidine sequences capable of adopting a number of superhelical stress-dependent structural configurations (left-handed helices and cruciforms), the question has been...

Biochem J
. 1996 Jun;
316 ( Pt 2):395-400.
PMID: 8687379
The 'tails' of histones H3 and H4 were removed by light in situ trypsin digestion of the nuclei. The alterations in the higher-order folding of chromatin resulting from this treatment...

. 1996 Apr;

PMID: 8619849
In the present study we have made attempts to estimate the effect of histone acetylation on the folding of the chromatin fibril into its high-order structures. Histones were modified directly...
