Description
EGF-TliA, EGF-LARD1 fusion proteins were secreted when ABC transporter was present. E. coli harboring the PrtDEF of E. chrysanthemi secreted more fusion proteins than without ABC transporter. In fact, in enzyme activation assay(with Hitachi Spectrophotometer) we observed that although our protein -EGF- has disulfide bonds, it was excreted succesfully. In addition, when compearing with lack of ABC domain, we saw that protein excretion into medium (supernatant) is 10-fold more with ABC transporter-PrtDEF-. PrtDEF functioned well at 37??C, the optimum growth temperature for E. coli
Notes
We used whole plasmid in order to excrete a fusion protein with one of two signal tags which are TliA and LARD1
