Genetic Blocks in the Isoleucine-valine Pathway of Neurospora Crassa.
A group of mutants of Neurospora crassa which require both isoleucine and valine have been described in a series of previous communications from this laboratory (WAGNER, SOMERS and BERGQUIST 1960; WAGNER, KIRITANI and BERGQUIST 1962; and KIRITANI 1962). These mutants were all found to be closely linked between the linkage group V markers Zys-1 (lysine-1, 33933) and sp (spray) within a segment a...
متن کاملSEPARATION OF MITOCHONDRIAL MEMBRANES OF NEUROSPORA CRASSA II. Submitochondrial Localization of the Isoleucine-Valine Biosynthetic Pathway
Separation of Neurospora mitochondrial outer membranes from the inner membrane/ matrix fraction was effected by digitonin treatment and discontinuous density gradient centrifugation . The solubilization of four isoleucine-valine biosynthetic enzymes was studied as a function of digitonin concentration and time of incubation in the detergent . The kinetics of the appearance of valine biosyntheti...
متن کاملDeacetylation of N-acetyl-L-glutamic acid by Neurospora crassa.
Photosynthetic bacteria and blue-green algae synthesize ornithine from glutamic acid by a cyclic route in which the intermediate N-acetylglutamic acid is regenerated by a transacetylation reaction; furthermore, in these microorganisms, arginine, which is synthesized from ornithine, is a specific inhibitor of N-acetyl-,y-glutamokinase which phosphorylates N-acetylglutamic acid on its y-carboxyl ...
متن کاملMutants with altered sensitivity to a calmodulin antagonist affect the circadian clock in Neurospora crassa.
Two newly isolated mutant strains of Neurospora crassa, cpz-1 and cpz-2, were hypersensitive to chlorpromazine with respect to mycelial growth but responded differently to the drug with respect to the circadian conidiation rhythm. In the wild type, chlorpromazine caused shortening of the period length of the conidiation rhythm. Pulse treatment with the drug shifted the phase and inhibited light...
متن کاملPhotoreception in Neurospora crassa: correlation of reduced light sensitivity with flavin deficiency.
The effect of flavin deficiency on blue light responses in Neurospora crassa was studied through the use of two riboflavin mutants (rib-1 and rib-2). The photoresponses assayed were the suppression of circadian conidiation, the phase shifting of the circadian conidiation rhythm, and the induction of carotenoid synthesis. Flavin deficiency was induced in the rib-1 mutant by restrictive growth te...
