Linkers in Biomacromolecules, Volume 647 in the Methods in Enzymology series, continues the legacy of this premier serial with quality chapters authored by leaders in the field. New sections in this updated release include chapters devoted to ser-gly linkers + models, sergGly- EAAAK linkers, Effect of crowding on linker behavior, Protathether. Experimental approach to quickly test different linkers in fusion proteins, Linkers in enzyme fusions/cascade catalysis, Linker dependence of avidity in multivalent interactions between disordered proteins, ER/K a-helix linker, The effect of chirality and steric hindrance on intrinsic backbone conformational propensities: tools for protein design, Linker design in protein-based nanostructures, and much more.
