EXPRESSION OF MENINGOCOCCAL FHBP POLYPEPTIDES |
摘要 |
The meningococcal fhbp gene (encoding factor H binding protein) is naturally expressed from two independent transcripts by two differentially regulated promoters. In one transcript it is co-expressed with the neighbouring upstream gene from the P nmb1869 promoter. The other transcript is monocistronic and is expressed from its own dedicated promoter, Pfhbp, which is activated by the global regulatory protein FNR in response to oxygen-limiting conditions. To increase expression of the monocistronic transcript a constitutively-active FNR mutant is used. The Pfhbp promoter can thus be activated, leading to over-expression of FNR-activated genes, such as fhbp. |
