The nitrate-reducing enzyme system of Chlamydomonas reinhardii

The nitrate-reducing enzyme system of Chlamydomonas reinhardii

J L Barea et al. Arch Microbiol. .

Abstract

In Chlamydomonas reinhardii the reduction of nitrate to ammonia occurs in two independent enzymatic steps: 1. the two-electrons reduction of nitrate to nitrite catalyzed by NADH-nitrate reductase, and, 2. the six-electrons reduction of nitrite to ammonia catalyzed by ferredoxin-nitrite reductase. Both enzymes have been purified and characterized, and some of their properties have been studied.
