S. aureus Extracellular Adherence Protein, Domains 3 and 4 Truncation, Bound to Cathepsin-G and Neutrophil Elastase

Abstract

This entry contains HT-SAXS data collected on samples of domains 3 and 4 of Eap from S. aureus strain Mu50, bound to two equivalents each of Cathepsin-G and Neutrophil Elastase. Models and interpretation of the data are available at the Small Angle Scattering Biological Data Bank (SASBDB) under entry SASDVP2. The reference for the journal article is: Mishra et al (2024) "S. aureus Eap is a polyvalent inhibitor of neutrophil serine proteases" J. Biol. Chem 300: 107627.

Experimental description

Data were collected at SIBYLS beamline 12.3.1 at Advanced Light Source in HT-SAXS mode. Samples of the protein complex were prepared at 5, 2.5, and 1.25 mg/ml protein in a buffer of 20 mM Hepes (pH: 7.4), 140 mM NaCl. The X-ray wavelength was set at λ=1.127 Å, and the sample to detector distance was 2100 mm, resulting in scattering vectors, q, ranging from 0.01 Å-1 to 0.45 Å-1. Experimental frames were analyzed after subtracting a background frame collected on the buffer alone, then averaged and merged using SAXS FrameSlice.
