Helicobacter pylori gamma-glutamyltranspeptidase (HpGT) is a general gamma-glutamyl hydrolase and a demonstrated virulence factor. The enzyme confers a growth advantage to the bacterium, providing essential amino acid precursors by initiating the degradation of extracellular glutathione and glutamine. HpGT is a

The aminopeptidase A of the porcine intestinal brush-border membrane has been purified following solubilization by trypsin (p-form) or Emulphogen (d-form). Full purification of d-amino-peptidase A required the use of anti-impurities immunoabsorbant chromatography. The d-amino-peptidase A constitutes about 4% of the
