Figure 4.
Fig. 4. Ribbon diagrams of HMk (cyan) aligned to various histone proteins. (A) HMk aligned to H2A-H2B (Luger et al. 1997). (B) HMk aligned to H3-H4 (Luger et al. 1997). (C) C-Terminal domain of HMk aligned to HMfB (Starich et al. 1996). (D) Superposition of HMk dimer created from the crystallographic 2-fold axis (cyan) and (H3-H4)[2] tetramer. Note the structural similarity between HMk and the other histones. Also note the similar arrangement of domains and interfaces between HMk and [H3-H4]. However, in the HMk structure, the C termini contact one another, whereas in the nucleosome structure the [H3-H4][2] has a gap. Structure alignments were performed using ALIGN (Satow et al. 1986).
