When folded chains formed from these proteins are elongated rather than globular, a "handshake" motif forms.
When folded chains formed from these proteins are elongated rather than globular, a "handshake" motif forms. Butyric acid inhibits enzymes like KAT which modify these proteins' lysine residues and allow the binding of a conserved bundle of four alpha helices called a (*) bromodomain. In sperm cells these are replaced by arginine-rich protamines. Ordered zigzags form when "linker" versions of these proteins form stems. These highly basic proteins can have their tail residues acetylated to regulate transcription. They come in five varieties and they make up a nucleosome. For 10 points, name these proteins designated H1 through H5 that act as a spool which DNA winds around to form chromatin.
