Poly(ADP-ribose) polymerase was purified from Ehrlich ascites-tumour cells by two novel methods. Analysis for amino acid composition revealed a high percentage of acidic amino acids or their amides, and of basic amino acids. N-Terminal analysis with dansyl chloride revealed no terminal amino acid, indicating a blocked N-terminal amino group. Analysis by gel electrophoresis of protein treated with 3-bromo-3-methyl-2-[(2-nitrophenylthio)-3H-indole, under conditions where selective cleavage of the polypeptide chain at tryptophan residues is obtained, showed six major peptide bands.

A 12 S globulin was isolated from each of the two species of rapeseed (B. napus L. and B. campestris L.) and they have been shown to be similar in terms of amino acid composition, amino terminal amino acids, number of subfractions, and carbohydrate content. One of the major proteins, a glycoprotein, present in each of the 12 S aggregates, was isolated and purified. Its amino acid composition, carbohydrate content, N-terminal amino acids, and sedimentation coefficient are reported herein.

The amino acid composition of 16-hr 6N HCI hydrolysates of three qualities of commercially classified wools has now been determined using the technique of Moore and Stein (1951). In this paper the results obtained on samples of Merino 70's and Corriedale 56's wool are compared with those previously reported for Merino wool of 64's quality. The overall pattern of the amino acid composition of the three wools is similar although small variations between the wools are observed with some of the amino acids.

Amino acid analyses of mitochondrial membranes are compared with the amino acid composition of whole mitochondria (Alberti, 1964) and found to be very similar except in the cystine content. The composition of the endogenous amino acids found in freshly prepared mitochondria has been established and shown to differ considerably from the amino acid composition of membranes or whole mitochondria. The amino acids produced during anaerobic incubation of mitochondria at pH7.4, on the other hand, resemble the membrane in composition, supporting the view that neutral proteinase activity is responsible for their appearance. Aerobic incubation produces a similar pattern of amino acids except that amino acids such as proline, serine, asparagine, glutamic acid and glutamine, which can be metabolically utilized under aerobic conditions, are present to a smaller extent. The presence of large relative concentrations of endogenous taurine, cysteic acid and oxidized glutathione and the accumulation of taurine during incubation is found. The selective retention of taurine and cysteic acid within the mitochondria is established. It is proposed that the first step in the degeneration of isolated mitochondria results from lipid hydroperoxide accumulation caused by the lack of glutathione reductase in isolated mitochondria.
