Kinetic Analysis of Lysozyme-Inhibitor Complex Formation

The structure of the proteinaceous inhibitor PliI from Aeromonas hydrophila in complex with its target lysozyme.

Recent microbiological data have revealed that Gram-negative bacteria are able to protect themselves against the lytic action of host lysozymes by secreting proteinaceous inhibitors. Four distinct classes of such inhibitors have been discovered that specifically act against c-type, g-type and i-type lysozymes. Here, the 1.24 Å resolution crystal structure of the periplasmic i-type lysozyme inhi...

Structure of the Neisseria Adhesin Complex Protein (ACP) and its role as a novel lysozyme inhibitor

Pathogenic and commensal Neisseria species produce an Adhesin Complex Protein, which was first characterised in Neisseria meningitidis (Nm) as a novel surface-exposed adhesin with vaccine potential. In the current study, the crystal structure of a recombinant (r)Nm-ACP Type I protein was determined to 1.4 Å resolution: the fold resembles an eight-stranded β-barrel, stabilized by a disulphide bo...

Structure-kinetic relationship analysis of the therapeutic complement inhibitor compstatin.

Compstatin is a 13-residue peptide that inhibits activation of the complement system by binding to the central component C3 and its fragments C3b and C3c. A combination of theoretical and experimental approaches has previously allowed us to develop analogs of the original compstatin peptide with up to 264-fold higher activity; one of these analogs is now in clinical trials for the treatment of ...
