We used this part as a negative control. We also have two other parts implying streptavidin non mutated, which are supposed to bien biotin (BBa_K1111012 and BBa_K1111014), and this streptavidin is mutated to decrease the Kd of the binding streptavidin-biotin. Thus, the streptavidin dead, although it is well exported to outer membrane, won't bind to biotin, or will bind weakly.

Ice Nucleation Protein fused to Streptavidin Dead

Introduction

It is a fusion protein between an Ice Nucleation Protein (INP) and Streptavidin Alive made by Gibson Assembly. INP is an outer membrane protein found in the genome of Pseudomonas syringae, that is recognize by the E.coli protein secretion machinery.

Usage and Biology

This part was designed to express streptavidin on the outer membrane of E.coli.
It serves as a negative control as the dead Streptavidin is though to not bind to biotin or with really decreased affinity.
