Abstract

We are investigating the kinetic effect of salt concentration on the reaction N2 + (6+2n)H+ + (6+2n)e- + 2(6+2n)ATP ­ 2NH3 + nH2 + 2(6+2n)Pi + 2(6+2n)ADP (1) catalyzed by nitrogenase where the spontaneous decomposition of S2O4 2- is the electron source. Under high partial pressures of N2, n has a limiting value of one, but in the absence of N2, nitrogenase simply catalyzes the reduction of protons to H2.
