Factor H binding protein (also known as GNA1870) is a surface exposed lipoprotein in Neisseria meningitidis that is a potent antigen and a potential candidate for a vaccine against meningococcal disease [1-4]. The structure of the C-terminal domain consists of an anti-parallel beta barrel overlaid by a short alpha helical region [1,5]. This domain is highly similar to Transferrin-binding protein B beta barrel (Pfam:PF01298).	Domain
