Design Notes

The coding sequence is driven by T7 promoter.

We added his tag to the N-terminal to facilitate purification of the expressed protein. Proline rich sequence put here is much longer than the length required for SH3 binding, for tighter binding to SH3 domain.

Proline rich sequence PVPPPVPPRRRP is from the structure of SH3 complexed with a proline rich peptide solved by Wittekind, et al. The Kd value is determined by them to be 3.57uM.

Source

mCherry sequence is from Clontech plasmid pmCherry-N1 and multi-proline sequence is synthesized from a consensus sequence of SH3 binding sequence.
