Effects of D-glutamate on mycelial growth and glutamate dehydrogenase enzymes of Coprinus lagopus.
D-Glutamate inhibited hyphal extension, the degree of inhibition depending on the identity of the glutamate dehydrogenase (GDH) enzyme present in the mycelium. Mycelia were most sensitive to inhibition on media which promoted formation of the NAD-linked GDH. The activity of this enzyme was inhibited by D-glutamate in experiments with cell-free extracts, the inhibitions being noncompetitive or m...
متن کاملFactors affecting the level and activity of pyruvate kinase from Coprinus lagopus sensu Buller.
The specific activity of Coprinus lagopus pyruvate kinase is high under conditions of glycolysis but low under conditions of gluconeogenesis. Only a single form of the enzyme was detectable, the properties of which resemble in a number of respects those of the allosteric forms of pyruvate kinase. These properties include co-operative interactions with phosphoenolpyruvate (PEP), ATP and fructose...
متن کاملThe mutagenic action of N-methyl-N'-nitro-N-nitrosoguanidine on Coprinus lagopus.
Optimal conditions, defined by the use of a known auxotrophic strain, are described for the mutagenesis of Coprinus Zagopus oidia by N-methyl-N’nitro-N-nitrosoguanidine (NTG), which is a very effective mutagen for bacteria and yeast. The oidia were best treated in phosphate buffer (PH 6.8) with a concentration of 15 pg. NTG/ml. for about 70 min. The yield of auxotrophs was considerably less tha...
متن کاملDark dependence of meiosis at elevated temperatures in the basidiomycete Coprinus lagopus.
Under continuous-light regimen Coprinus lagopus can enter and complete meiosis at 25 C, but is unable to do so at 35 C. The temperature-sensitive and the dark-dependent period is 10 hr before karyogamy. It is conjectured that the basidia are programmed for the initiation of meiosis during that 10-hr period.
متن کاملMutants of Coprinus lagopus selected for resistance to 2-Deoxy-D-glucose
The glucose analogue 2-deoxy-D-glucose seriously inhibits the growth of Coprinus lagopus. Following treatment with iV-methyl-iV'-nitro-i^nitrosoguanidine 388 resistant mutants were isolated. It is shown that the mutants isolated are probably allelic; they were phenotypically similar and no complementation was observed. The mutants were pleiotropic in the sense that although they were initially ...
