encodes removable tag for protein isolation
expression vector
vector permitting RNA synthesis in vitro
vector permitting construction of fusion proteins
Restriction digests of the clone give the following sizes (kb): BamHI--5.6; NcoI--5.6; SstI--5.6.
The thrombin cleavage sites produced in the protein enable the release of the fused protein from the GST tag.
The order of the major features in the plasmid is: T7 promoter - NcoI - SacI - thrombin I encoding site - GST coding sequence - thrombin II encoding site - BamHI - ampR - pMB1 ori.
The plasmid yield is rather low and thrombin cleavage of the fusion proteins can be inefficient.
Expression vector allowing production of an N-terminal or C-terminal fusion to glutathione S-transferase (GST) for affinity purification of the recombinant protein.
