1.1.98.6	?	x * 84100, calculated, x * 74000 and x * 84000, due to truncation of protein at the site of the glycyl radical, SDS-PAGE	
1.1.98.6	dimer	2 * 77000, SDS-PAGE	
1.1.98.6	heterotetramer	2 * 17500, small subunit alpha, plus 2 * 80000, large subunit beta	
1.1.98.6	additional information	occurence of a degradation product named beta2 of 74000 Da	
1.1.98.6	additional information	the large and the small proteins form a tight complex with 1:1 stoichiometry. The anaerobic reductase thus has an alpha2beta2 structure
