General Information
Protegen ID 808
Sequence Strain (Species/Organism) Helicobacter pylori
VO ID VO_0011339
Taxonomy ID 210
Other Database IDs CDD:163712
Molecule Role Protective antigen
Molecule Role Annotation Recombinant H. pylori catalase plus CT was used for immunization, and groups of mice were challenged with the Sydney strain of H. pylori. Immunization with recombinant catalase protected a significant proportion (9 of 10) of the mice from H. pylori challenge, indicating that this enzyme should be considered as a candidate for a future vaccine (Radcliff et al., 1997).

Significant protection against H. pylori colonisation was induced with rSOD, rKatA and rTpx individually (Stent et al., 2012).
