Uptake of nitrite by Neurospora crassa.
Like the nitrate transport system, the nitrite uptake system in Neurospora crassa is induced by either nitrate or nitrite. This induction is prevented by cycloheximide, puromycin, or 6-methyl purine. The K(m) for nitrite of the induced nitrite uptake system is 86 muM, and the V(max) is 100 mumol of nitrite per g (wet weight) per h. Nitrite uptake is inhibited by metabolic poisons such as arsena...
متن کاملTechniques for augmentation of exogenous DNA uptake by ovine spermatozoa
Sperm mediated gene transfer can be an inexpensive and simple method in animal transgenesis; however its efficiency is poor, mainly due to the spermatozoa’s lesser uptake of exogenous DNA. In the present study, the effects of lipofection and other augmentation techniques, such as sperm freezing and spermatozoa treatment with triton X100 and DMSO, on exogenous DNA uptake by sheep spermatozoa and...
متن کاملGuanine uptake and metabolism in Neurospora crassa.
Guanine is transported into germinated conidia of Neurospora crassa by the general purine base transport system. Guanine uptake is inhibited by adenine and hypoxanthine but not xanthine. Guanine phosphoribosyltransferase (GPRTase) activity was demonstrated in cell extracts of wild-type germinated conidia. The Km for guanine ranged from 29 to 69 micro M in GPRTase assays; the Ki for hypoxanthine...
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 کاملImpact of 15N-labeled rice straw and rice straw compost application on N mineralization and N uptake by rice
Incorporation of plant residues in soil affects N and C content and dynamics. This studydetermined the effects of short-term alternative rice (Oryza sativa L.) residue management on Nmineralization and uptake by rice. Pot and laboratory incubation experiments were established byincorporating 15N-labeled rice straw and rice straw compost in paddy soil. The 15N recovered by riceaveraged 16.6%; mo...
