ISWI-family enzymes remodel chromatin by sliding nucleosomes along DNA, but the nucleosome translocation mechanism remains unclear. Here we use single-molecule FRET to probe nucleosome translocation by ISWI-family remodelers. Distinct ISWI-family members translocate nucleosomes with a similar stepping pattern maintained by the catalytic subunit of the enzyme. Nucleosome remodeling begins with a...
A highly repeated DNA was isolated from the West African baboon (Papio papio) as a 343-base-pair fragment after digestion of total baboon DNA with the restriction endonuclease BamHI. The DNA sequence of this fragment was obtained by chemical cleavage methods and is compared with the DNA sequence of related highly repeated primate DNAs from African green monkey (Cercopithecus aethiops) and man. ...
A statistical method is developed to estimate the maximum amplitude of base pair fluctuations in a three dimensional mesoscopic model for nucleic acids. The thermal vibrations around helix diameter are viewed as Brownian motion particle embedded stable helical structure. probability return initial position computed, function time, by integrating over paths consistent with physical properties po...
