Mechanism and importance of post-translational regulation of nitrate reductase.

Journal of experimental botany - 1 Jun 2004

Lillo Cathrine, Meyer Christian, Lea Unni S, Provan Fiona, Oltedal Satu

Abstract excerpt

In higher plants, nitrate reductase (NR) is inactivated by the phosphorylation of a conserved Ser residue and binding of 14-3-3 proteins in the presence of divalent cations or polyamines. A transgenic Nicotiana plumbaginifolia line (S521) has been constructed where the regulatory, conserved Ser 521 of tobacco NR (corresponding to Ser 534 in Arabidopsis) was mutated into Asp. This mutation resulted in the complete...
