The inhibitor protein (IP) that inactivates spinach leaf NADH:nitrate reductase (NR) has been identified for the first time as a member of the eukaryotic 14-3-3 protein family based on three lines of evidence. First, the sequence of an eight amino acid tryptic peptide, obtained from immunopurified IP, matched that of a highly conserved region of the 14-3-3 proteins. Second, an authentic member of the 14-3-3 family, recombinant Arabidopsis GF14omega, caused inactivation of phospho-NR in a magnesium-dependent manner identical to IP. Third, an anti-GF14 monoclonal antibody cross-reacted with IP and anti-IP monoclonal antibodies cross-reacted with GF14omega.
