Nicotinamide adenine dinucleotide-specific glutamate dehydrogenase of Neurospora. V. Tryptic peptides

Abstract

The isolation and sequences of an additional 80 peptides from a tryptic digest of the NAD-specific glutamate dehydrogenase of Neurospora crassa are reported. These include an additional peptide containing a lysine residue labeled at the epsilon-amino group with pyridoxal 5'-phosphate. The sequence of this peptide shows some homology with the reactive lysine residue of other glutamate dehydrogenases.
