THE SOLUTION STRUCTURE OF THE ACTIVE DOMAIN OF CAP18: A LIPOPOLYSACCHARIDE BINDING PROTEIN FROM RABBIT LEUKOCYTES
Overview
We have employed the circular dichroism (CD) technique to characterize the, solution structure of CAP18(106-137), a lipopolysaccharide (LPS) binding, antimicrobial protein, and its interaction with lipid A. Our results, revealed that CAP18(106-137) may exist in at least three lipid A, concentration-dependent, primarily helix conformations. The 'model', structure of CAP18(106-137) in 30% (v/v) TFE, determined by nuclear, magnetic resonance (NMR) technique, was found to be a complete and very, rigid helix. In this conformation, the cationic and hydrophobic groups of, CAP18(106-137) are separated into patches and stripes in such a way that, it can favorably interact with lipid A through either coulombic, interaction with the diphosphoryl groups or hydrophobic interaction with, the fatty acyl chains.
