Nicotinamide adenine dinucleotide-specific glutamate dehydrogenase of Neurospora. VI. Isolation and sequences of eighteen fragments from the cyanogen bromide digest
B. M. Austen, J. F. Nyc and E. L. Smith
The 1030-residue polypeptide chain of the NAD-specific glutamate
dehydrogenase of Neurospora crassa was fragmented by treatment with
cyanogen bromide. The isolation and sequences of 18 fragments ranging in
size from 4 to 51 residues are described. Some of these peptides proved to
be cleavage products resulting from hydrolysis at acid-sensitive
aspartyl-prolyl bonds. Some overlaps could be deduced on the basis of known
sequences of peptides obtained by tryptic hydrolysis.
