The mechanism of the denitrification and nitrosation reactions catalyzed by the heme cd-containing nitrite reductase from Pseudomonas stutzeri JM 300 has been studied with whole cell suspensions using H2(18)O, 15NO, and 15NO-2. The extent of H2(18)O exchange with the enzyme-bound nitrosyl intermediate, as determined by the 18O content of product N2O, decreased with increasing nitrite concentration, which is consistent with production of N2O by sequential reaction of two nitrite ions with the… CONTINUE READING
