    Notes: Abstract The initial reactions possibly involved in the acrobic and anaerobic metabolism of aromatic acids by a denitrifying Pseudomonas strain were studied. Several acyl CoA synthetases were found supporting the view that activation of several aromatic acids preceeds degradation. A benzoyl CoA synthetase activity (AMP forming) (apparent K m values of the enzyme from nitrate grown cells: 0.01 mM benzoate, 0.2 mM ATP, 0.2 mM coenzyme A) was present in aerobically grown and anaerobically, nitrate grown cells when benzoate or other aromatic acids were present. In addition to benzoate and fluorobenzoates, also 2-amino-benzoate was activated, albeit with unfavorable K m (0.5 mM 2-aminobenzoate). A 2-aminobenzoyl CoA synthetase (AMP forming) was induced both aerobically and anaerobically with 2-aminobenzoate as growth substrate which had a similar substrate spectrum but a low K m for 2-aminobenzoate (〈0.02 mM). Anaerobic growth on 4-hydroxybenzoate induced a 4-hydroxybenzoyl CoA synthetase, and cyclohexanecarboxylate induced another synthetase. In contrast, 3-hydroxybenzoate and phenyl-acetate grown anaerobic cells appeared not to activate the respective substrates at sufficient rates. Contrary to an earlier report extracts from aerobic and anaerobic 2-aminobenzoate grown cells catalysed a 2-aminobenzoyl CoA-dependent NADH oxidation. This activity was 10–20 times higher in aerobic cells and appeared to be induced by 2-aminobenzoate and oxygen. In vitro, 2-aminobenzoyl CoA reduction was dependent on 2-aminobenzoyl CoA NAD(P)H, and oxygen. A novel mechanism of aerobic 2-aminobenzoate degradation is suggested, which proceeds via 2-aminobenzoyl CoA.

    Description / Table of Contents: Reaction Products of Carbamoyl Azides with Antimony(V) Chloride resp. Hydrogenchloride/Antimony(V) ChlorideCarbamoyl azides react with antimony(V) chloride to form the 1:1-addition compounds. By i.r. spectroscopy could be shown that the Lewis acid is added to the carbonyl group. Hydrogenchloride/antimony(V) chloride leads to oxygen-protonated carbamoyl azides. The i.r. spectra were assigned.
    Notes: Carbamoylazide reagieren mit Antimon(V)-chlorid unter Bildung von 1:1-Addukten. IR-Spektroskopische Untersuchungen zeigen, daß die Lewis-Säure an das Carbonyl-Sauerstoffatom gebunden ist. Mit Chlorwasserstoff/Antimon(V)-chlorid bilden sich die am Sauerstoff protonierten Carbamoylazide. Die IR-Spektren wurden zugeordnet.
