Fig. 1. Schematic structures and sequences of branched and linear peptides.

Fig. 1

Branched peptides are composed of a three-lysine core, with four branches attached at the four amino groups (N-terminal) of the core. The 20-mer linear H2K peptides have a sequence similar to a branch of H2K4b. The predominant repeating groups are underline. Labeled histidines (U-15N3) and lysines (U-13C6 and U-15N2) are represented by arrows.
