The authors report that in Figure S4 the value 1.63 of NrfA Ve/V0 is incorrect due to a typo and that the actual value of NrfA Ve/V0 is 1.93. Using this the corrected Ve/V0 value of 1.93 results in a calculated NrfA molecular weight of approximately 52 kDa. This new calculated value agrees well with the actual molecular weight of NrfA (∼56 kDa), and it further supports the conclusion that NrfA behaves as a monomer in solution under these conditions.
