Abstract:
A cell-based assay for identifying a compound that inhibits iron transport in Gram-negative bacteria, engineered bacterial cells, and kits for conducting the same. The assay involves contacting a candidate compound with an engineered Gram-negative bacteria in the presence of iron for a sufficient period of time, exposing the reaction solution to an energy source to generate the detectable signal, and detecting changes in the detectable signal in the reaction solution over time. The engineered Gram-negative bacteria comprises an iron transport protein on its outer membrane that comprises an amino acid residue that has been engineered with a detectable label that generates a detectable signal. The changes in the detectable signal in the assay system over time correspond to the effect of the candidate compound on iron transport in the Gram-negative bacteria.

Abstract:
The present invention relates to isolated nucleic acid molecules which encode an antigen from a Moraxella catarrhalis (Meat) species, a vector which comprises such nucleic acid molecule, and a host cell comprising such vector. Furthermore, the invention provides antigens from a Moraxella catarrhalis species, as well as fragments and variants thereof, a process for producing such antigens, and a process for producing a cell which expresses such antigen. More specifically, such antigens are produced by or associated with bacterial infections caused by Moraxella catarrhalis. Moreover, the present invention provides antibodies binding to such antigen, a hybridoma cell producing such antibodies, methods for producing such antibodies, a pharmaceutical composition comprising such nucleic acid molecule, antigen, vector or antibody, the use of such nucleic acid molecule, antigen, vector or antibody for the preparation of a pharmaceutical composition, methods for identifying an antagonist capable of binding such antigen or of reducing or inhibiting the interaction activity of such antigen, methods for diagnosing an infection with Moraxella catarrhalis and methods for the treatment or prevention of an infection with Moraxella catarrhalis.
Abstract:
Provided is a nucleic acid molecule comprising the sequence is set forth in SEQ ID NO:1, the corresponding protein sequence as set forth in SEQ ID NO:2, and variants and functional fragments thereof.
