【Significance】
Unwrapping outer superhelical turn of CENP-A nucleosome
Because histone proteins have their variants and are subject to posttranslational modification, there are a variety of
constitutions for nucleosomes which are the fundamental structural unit of chromatin. To investigate differences between the canonical H3 nucleosome and a H3 variant, CENP-A nucleosome, free energy profile for DNA unwrapping of CENP-A nucleosome was calculated. The profile shows that 16 to 22 bp unwrapped states are the most stable for CENP-A nucleosome, indicating that the CENP-A nucleosome is poised to provide scaffolds for kinetochore proteins.
