| Overview | Origami™ 2 host strains are K-12
derivatives that have mutations in both the
thioredoxin reductase (trxB) and glutathione
reductase (gor) genes, which greatly enhance
disulfide bond formation in the E. coli
cytoplasm.
The Origami
2 strains are kanamycin sensitive; like the
original Origami strains, the gor mutation is still selected
for by tetracycline. To reduce the possibility of
disulfide bond formation between molecules,
strains containing mutations in trxB and gor are
recommended only for the expression of proteins
that require disulfide bond formation for proper
folding.
DE3 indicates that the host is a lysogen of λDE3, and therefore carries a chromosomal copy of the T7 RNA polymerase gene under control of the lacUV5 promoter. Such strains are suitable for production of protein from target genes cloned in pET vectors by induction with IPTG. |
