title: NH 2 -terminal residues of Neurospora crassa proteins.
abstract: The NH(2)-terminal amino acid composition of the soluble and ribosomal proteins from Neurospora crassa mycelia and conidia was determined by the dinitrophenyl method. A nonrandom distribution of NH(2)-terminal amino acids was observed in the complex protein mixtures. Glycine, alanine, and serine accounted for 75% of the NH(2)-terminal amino acids, and glycine appeared most frequently in mature proteins of mycelia. The appearance of phenylalanine as one of the major NH(2)-termini in crude conidial fraction suggests that the composition of proteins may vary in different developmental stages.
