R34 heterodimerizing leucine zipper

Engineered Leu zipper based on VBP B-ZIP domain that forms medium-weak parallel heterodimers with variants E34(X). This zipper corresponds to RR34(A) in Acharya et al and R34 in Bashor et al. Bashor et al. used the three different pairs to tune the affinity of their MAPK feedback device.

Interaction with E34(X) variants:

• E34(I): Kd = 6.1 nM = J18923

• E34(V): Kd = 41 nM

• E34(N): Kd = 810 nM
