Identification of nitric oxide and nitrous oxide as products of nitrite reduction by Pseudomonas cytochrome oxidase (nitrite reductase)

Both NO and N 2O were identified by GC/MS as gaseous products of nitrite reduction catalyzed by the cytochrome oxidase (nitrite reductase) purified from Pseudomonas aeruginosa. Gas production was inhibited by cyanide. The enzyme also catalyzed the reduction of NO to N 2O. No N 2 was identified as a...

Zusammenfassung:	Both NO and N 2O were identified by GC/MS as gaseous products of nitrite reduction catalyzed by the cytochrome oxidase (nitrite reductase) purified from Pseudomonas aeruginosa. Gas production was inhibited by cyanide. The enzyme also catalyzed the reduction of NO to N 2O. No N 2 was identified as a consequence of either nitrite or NO reduction.
