    Notes: Abstract— The formation of N-acetyl-aspartyl-peptides in mouse brain homogenates is described. The formation is completely dependent on histamine and on an ATP-regenerating system, and partially dependent on the addition of N-acetyl-aspartate and certain other amino acids. The N-acetyl-aspartyl-peptide formation is probably non-ribosomal and is apparently not due to hydrolysis of preformed proteins.

    Notes: Abstract— The isolation of a perchloric acid-soluble low molecular weight protein from brain of Macaca irus is reported. Sodium dodecyl sulphate polyacrylamide gel electrophoresis and gel isoelectric focusing indicate that the protein is free of impurities. The molecular weight, as determined by gel filtration and sodium dodecyl sulphate gel electrophoresis, is shown to be 10,400 and 9900, respectively. This is in agreement with the value of 10,700 obtained from amino acid analysis. The protein contains 27 per cent acid amino acids and 15 per cent basic amino acids. However, the relatively high amide content gives the protein a neutral nature as shown by isoelectric point determination using gel isoelectric focusing.

    Notes: The isolation of two acid-soluble proteins from Macaca irus brain is reported. The proteins contained 34 and 35.6 per cent polar amino acids, respectively. One protein had a mol. wt. of approx. 37,100 and the other of 23,000 with subunits of 11,500. Each protein contained 4′-phosphopantetheine, which was hydrolytically determined as taurine and β-alanine and microbiologically as pantothenate. The smaller protein is found to be present in the supernatant following homogenization both in 0-32 M-sucrose and in 0-32 M-sucrose with 40 mm-NaCl. The larger protein is also mainly present in the supernatant fluid. The function of these proteins is unknown, but the mol. wt. 23,000 species could be acetylated from glucose and acetate in mouse brain tissue slices and the acetyl groups could be isolated as the hydroxamate.

    Notes: The effect of some biogenic amines and amino acids on the level of N-acetyl-asparticacid and N-acetyl-aspartyl-glutamic acid has been investigated in mouse brain tissue slices. The amines all caused a significant decrease in the levels of N-acetyl-aspartic acid and N-acetytl-aspartyl-glutamic acid within 5 min of incubation, while the amino acids, in spite of being possible transmitter candidates, had no such effect.
