Brucella abortus | live attenuated Salmonella typhimurium (ST) vector constitutively expressing heterologous Brucella abortus S19 PrpA protein (ST-PrpA) is inoculated in BALB/c mice. No aggravation of morbidity is observed upon mice inoculation of ST-PrpA. Immunized mice show significantly quicker anti-Salmonella IgG responses as compared to ST only immunization, and an increase interleukin-4 production evident in in vitro pulsed mice splenocytes, splenocytes proliferative profiles and lymphocyte population evaluation, overview | up |
General Information | Comment | Organism |
---|---|---|
evolution | 4-hydroxyproline 2-epimerase is a member of proline racemase family | Brucella abortus |
physiological function | the enzyme 4-hydroxyproline 2-epimerase reversibly catalyse the interconversion of trans-4-hydroxy-L-proline and cis-4-hydroxy-D-proline. The Brucella proline racemase (PrpA) or hydroxyproline epimerase (BaHyPRE) also exhibit B-cell mitogenic properties thereby causing B-lymphocytes polyclonal activation and increase secretion of interleukin (IL)-10.
