Noun
octamer (plural octamers)
An oligomer having eight subunits
In addition, non-polar interactions are made between protein side-chains and the deoxyribose groups, and an arginine side-chain intercalates into the DNA minor groove at all 14 sites where it faces the octamer surface. Source: Internet
The histone octamer is formed by a central H3/H4 tetramer sandwiched between two H2A/H2B dimers. Source: Internet
Nucleosome positions are controlled by three major contributions: First, the intrinsic binding affinity of the histone octamer depends on the DNA sequence. Source: Internet
These are due to the formation of two types of DNA binding sites within the octamer; the α1α1 site, which uses the α1 helix from two adjacent histones, and the L1L2 site formed by the L1 and L2 loops. Source: Internet
