Numerous forms of Bartonellosis are caused by Bartonella henselae as well as Cat Scratch Disease & Bacillary Angiomatosis. It has been found that up to 95% of patients with Cat Scratch Disease show antibodies against Bartonella henselae antigens. Highly immunoreactive proteins which are produced by the Bartonella henselae are the most important antigens used for the diagnosis of Cat Scratch Disease. The immunogenic protein dihydrolipoamide-succinyltransferase also named SucB is an enzyme of the alpha-ketoglutarate dehydrogenase complex, which catalyzes the transport of a succinyl group from the S-succinyldihydrolipoyl moiety to coenzyme A.
Recombinant Bartonella Henselae SucB produced in E.Coli is a single, non-glycosylated polypeptide chain having a molecular mass of 45kDa.Bartonella SucB is expressed with a -10x His tag at N-terminus and purified by proprietary chromatographic techniques.
