Expression and characterization of C-terminal truncated mutants of γ-glutamyltranspeptidase II (PaGGTII) from Pseudomonas aeruginosa PAO1.

The gene encoding γ-glutamyltranspeptidase II (PaGGTII) from Pseudomonas aeruginosa PAO1 was cloned in Escherichia coli. Recombinant PaGGTII showed a weak activity (0.0332 U/mg), and it can be easily inactivated.
