the enzyme is involved in aerobic assimilatory nitrate reduction. The enzyme enables Haloferax alexandrinus to use nitrate as sole nitrogen source for growth under aerobic conditions. Haloferax alexandrinus may induce denitrification under anaerobic or microaerobic conditions using nitrate as electron acceptor
