Stutzerimonas chloritidismutans
-
SDS-PAGE, native enzyme with Superdex 200 column with 50 mM potassium phosphate buffer, pH 7.0 and 100 mM NaCl
140000
155000
pentamer, native mass spectrometry, native mass spectrometry, enzyme buffer-exchanged to 50 mM ammonium acetate, pH 6.8, with centrifugal filter units with 30 kDa cutoff
28400
30000
30420
monomer without heme, native mass spectrometry, enzyme buffer-exchanged to 50 mM ammonium acetate, pH 6.8, with centrifugal filter units with 30 kDa cutoff

Stutzerimonas chloritidismutans
-
4 * 31000, heme content 1.5 mol Fe2+/mol enzyme (calculated from Soret peak shift measurement), 2.2 mol Fe2+/mol enzyme (metal analysis by ICP-MS)
31030
monomer with heme, native mass spectrometry, enzyme buffer-exchanged to 50 mM ammonium acetate, pH 6.8, with centrifugal filter units with 30 kDa cutoff
4 * 30000 Da, elution position on a gel-filtration column using Stokes radius to determine molecular weight points to globular tetramer, collisional activation of the ions ejects one monomer of the pentamer, so that low-charged tetramer counter complex ions are also observed with native mass spectrometry
30000
5 * 30000 Da, tandem mass spectrometry, native mass spectrometry, active state in solution
30000
6 * 30000, multiple anomalous dispersion crystal structure, one heme per monomer (histidine 170 axial heme ligand), arginine 183 probably with essential role in substrate positioning and activation, activity of the hexamer not measurable because of the presence of the thiocyanate inhibitor, each monomer appears to be acting on its own, therefore, different quaternary states may be biologically relevant depending on protein concentration, pH, or other factors
