1 Histone H1 and the compaction of nucleosomal arrays A key molecule in directing the formation of higher order structure in a nucleosomal array is the linker histone H1. However, histone H1 is not essential for chromatin folding. The folding of histone HI-deficient chromatin provides us with important insights into how and why nucleosomal arrays are compacted. , 1992). Under appropriate conditions it is possible to compact chromatin to the level approximately the same as that observed in vivo (Schwarz and Hansen, 1994).

Considerable evidence exists in support of sequencedirected positioning of nucleosomes on DNA. For example, chicken and frog core histones in vitro and yeast histones in vivo all recognize the same structural features of a 5S ribosomal RNA gene which direct nucleosome position (Fig. 22; Simpson, 1991). Mutagenesis experiments in which DNA sequences in and around the 5S RNA gene were perturbed indicate that a region comprising 20-30 bp to either side of the centre of nucleosomal DNA contains the elements necessary for positioning (FitzGerald and Simpson, 1985).

Lower panel: addition of linker histone (black) immobilizes nucleosomes, fixes position and constrains linker DNA. sequence-selective interaction of the globular domain of H1 with nucleosomal DNA has an important role in stabilizing the 5S nucleosome. 1). The capacity of histone H1 to bind to nucleosomal DNA in a sequence-selective manner explains the positioning of nucleosomes on the Xenopus oocyte-type 5S rRNA gene in vivo (Chipev and Wolffe, 1992; Sera and Wolffe, 1998). , 1995). , 1993). 2).
