T IS possible by means of X-ray or ultraviolet treatment to produce mutant I strains of Neurospora crassa that are deficient in their abilities to synthesize specific vitamins, amino acids, or other essential substances (BEADLE and TATUM 1941; TATUM and BEADLE 1g4zb). It occurred to us that it might be possible to determine whether the mutant genes concerned in such haploid strains are recessiv...
We describe the synthesis of novel mononuclear and dinuclear copper complexes and an investigation of their behaviour in solution using mass spectrometry (ESI-MS and ESI-MS/MS) and in the solid state using X-ray crystallography. The complexes were synthesized from two widely used diacetylpryridine (dap) ligands, i.e. 2,6-diacetylpyridinebis(benzoic acid hydrazone) and 2,6-diacetylpyridinebis(2-...
During recent years many experiments have demonstrated the usefulness of antimetabolites for studying routes of metabolism. Competitive inhibitors have been used to block specific enzyme systems and to establish enzyme-substrate relationships, and the compounds produced by the action of these enzyme systems have been characterized through their ability to enhance the reversal of the inhibitors ...
