Figure 7From: Molecular dynamics and mutational analysis of the catalytic and translocation cycle of RNA polymeraseProposed interactions between bridge helix switch residues β’ H1075 and K1079 and the fork region. Fork residues β R420, D426 and D429 are proposed from simulations to be switch residues. Interacting residues β R142 and R331 also appear to be involved in the switching mechanism.Back to article page
