The Use of Photolysis of Dinitrophenyl-peptides in Structural Studies on the Cell-Wall Mucopeptide of Corynebacterium poinsettiae

The photochemical behaviour of DNP-amino acids and peptides was studied by Russell (1963a). He found that when the DNP-derivatives of most a-amino acids were dissolved in 1% (w/v) NaHCO3 and exposed to light, the link between the amino group and the aliphatic chain was cleaved to yield NNAt, carbon dioxide and the aldehyde produced
