title: Nicotinamide adenine dinucleotide-specific glutamate dehydrogenase of Neurospora crassa. Isolation and sequences of several cyanogen bromide peptides from the NH2-terminal portion of the peptide chain.
abstract: Previous studies of the amino acid sequence of the NAD-specific glutamate dehydrogenase of Neurospora crassa (EC 1.4.1.2) resulted in the assignments of peptides to four fragments, the longest being the COOH-terminal 669 residues of the protein. A further study of peptides derived by cyanogen bromide cleavage by different separation methods has yielded additional peptides that have provided new information concerning the sequence and has given overlaps of previously known sequences. This has permitted establishment of 313 residues in one sequence (fragment II). This is in addition to a sequence of 43 residues (fragment I) at the NH2-terminal end and a sequence of 669 residues (fragment III) previously established at the COOH-terminal end of the molecule. The present status of our knowledge of the overall sequence is given in the accompanying papers, together with some views regarding the conformation of the protein (Haberland, M.E., Chen, C.-W., and Smith, E.L. (1980) J. Biol. Chem. 255, 7993-8000, and Austen, B.M., Haberland, M.E., and Smith, E.L. (1980) J. Biol. Chem. 255, 8001-8004).
