The title compound, C19H17PS2, results from the direct deprotonation of di-phenyl-methyl-phosphine sulfide and subsequent reaction with diphenyl di-sulfide. The C-P and C-S bond lengths of 1.8242 (18) and 1.8009 (18) Å, respectively, of the central P-C-S linkage are comparable to those found in the sulfonyl analogue, but are considerably longer than those reported for the dimetallated sulfonyl ...

An engineered variant of the protease subtilisin from Bacillus amyloliquefaciens, in which the D32A mutation renders the enzyme's activity dependent on the presence of certain small anions such as fluoride or azide, has been produced. This modified enzyme has applications as an azide or fluoride-triggered expression-purification tool. We report activity measurements showing that the enzyme is a...

The dissociation of respiration from synthetic processes by azide was shown by studies of Clifton in 1937 (1) and by the results of subsequent investigations (24). Hotchkiss in 1944 made the significant observation that, although bacterial respiration was enhanced by azide, inorganic orthophosphate (Pi) uptake was decreased (5). The ability of azide to uncouple oxidation of substrates from net ...

1. The inhibition of the oxidase activity of caeruloplasmin by azide was investigated at 25 degrees and 7.5 degrees . 2. The inhibition is reversible on dilution or Sephadex treatment, indicating a caeruloplasmin-azide complex. 3. The enzyme is protected against azide inhibition by chloride, acetate or EDTA, the last-named acting not by chelation but by a non-specific effect similar to that of ...
