Class 1 outer membrane protein PorA of Neisseria meningitidis is a vaccine candidate against bacterial meningitis. Antibodies against PorA are able to induce complement-mediated bacterial killing and thereby play an important role in protection against meningococcal disease. Bactericidal antibodies are all directed against variable regions VR1 and VR2 of(More)
On the basis of deuterium labeling experiments and an equal 1,2-/1,4-product distribution, the reductive elimination of the product has been established to be the enantioselective step in the nickel-catalyzed hydrocyanation of 1,3-cyclohexadiene. This could be achieved by successfully exploiting the rather unique features of this reaction: identical product(More)
An antibody-peptide model system was used to study the binding characteristics between a bactericidal antibody (MN12H2) and the P1. 16 epitope of class 1 outer membrane protein PorA of Neisseria meningitidis by means of a thermodynamic approach. A series of four linear peptides and three "head-to-tail" cyclic peptides (with ring sizes of 9, 15 and 17 amino(More)
This paper describes a method for determining the affinity constant (Ka) of the binding between an antibody Fab fragment and a membrane-embedded protein epitope under equilibrium conditions. Monoclonal antibody MN12H2, directed against outer membrane protein PorA of Neisseria meningitidis, is used in a competitive fluorescence polarization assay with a(More)
