A sequence is presented for the COOH-terminal 669 residues of the NAD-specific glutamate dehydrogenase of Neurospora crassa. Comparison of this sequence with those of the vertebrate glutamate dehydrogenases of chicken and bovine liver and with the NADP-specific enzyme of Neurospora shows some similarities in sequences around residues previously identified as important for the function of these enzymes. These are: (a) the reactive lysine residue of low pK in the NADP and the vertebrate enzymes; (b) the tyrosine residue of the NADP enzyme that is readily nitrated by tetranitromethane with inactivation, a residue protected by NADP or by NMN; and (c) the arginine residue of the NADP-enzyme that is reactive with 1,2-cyclohexanedione with inactivation. Despite these similarities, comparison of the sequence of the NAD-enzyme with those of the other glutamate dehydrogenases of known sequences revealed relatively little overall homology as determined by computer analysis. |
