pTWIN1 is an E. coli expression vector designed for protein purification or for the isolation of proteins with an N-terminal cysteine and/or a C-terminal thioester. A polylinker in the vector is designed for the in-frame fusion of a target gene between the modified Ssp DnaB and Mxe GyrA inteins. The presence of the chitin binding domain from Bacillus circulans facilitates purification.
pTWIN1 is an E. coli expression vector which can be used with the IMPACT™ Kit (NEB #E6901). pTWIN vectors are designed for protein purification or for the isolation of proteins with an N-terminal cysteine and/or a C-terminal thioester (1). A polylinker in the vector is designed for the in-frame fusion of a target gene between the modified Ssp DnaB (2) and Mxe GyrA inteins (3,4). The presence of the chitin binding domain from Bacillus circulans (5,6) facilitates purification. The double-stranded vector is 7,375 base pairs in length.
