HlyA-tag+Secretion system

Introduction

The alpha-hemolysin system is one of the best-studied type 1 secretion systems (T1SS) of E. coli. In T1SS the secretion occurs in a single step directly from the cytosol to the extracellular medium. The secretory machinery of the alpha-hemolysin system consists of three proteins: HlyB, an ATP binding cassette; HlyD, a membrane fusion protein; and TolC, an outer membrane protein (Su, et al., 2012).

Usage

This is a device that allows a protein to be secreted by means of the alpha-hemolysin secretion system in E. coli. It’s designed so that the only thing that you have to do is to assemble your protein part in the device via the biofusion standard (BBF RFC 23), (Cut the device with EcoRI and XbaI, cut your protein part with EcoRI and SpeI, mix & ligate). This procedure will leave your part in frame with a signal peptide.

Note: It’s important that your part doesn’t contain a stop codon nor a terminator since your protein will be fused at the C-terminus.
