FIG. 1.
Diagram of plasmid pVT1394. The map indicates the location of the cloned pepO gene of S. parasanguis in the expression vector pET28a. The shaded arrow indicates the direction of transcription of the pepO gene. NcoI and HindIII indicate the location of restriction enzyme sites used for insertion of pepO into the vector in frame with sequences encoding the hexahistidine tag.
