Regulation of glutamine synthetase ec 6.3.1.2 in fed batch cultures of neurospora crassa


, : Regulation of glutamine synthetase ec 6.3.1.2 in fed batch cultures of neurospora crassa. Biochemical and Biophysical Research Communications 78(4): 1234-1240

The effect of the N and C sources in the regulation of glutamine synthetase [EC 6.3.1.2] was studied in fed-batch cultures of N. crassa. The limitation of ammonium in an excess of the C source, leads to an accumulation of .alpha.-ketoglutarate and elevation of glutamine synthetase. The limitation of sucrose in an excess of ammonium results in a decrease in glutamine synthetase activity. Apparently the C source exerts a positive control in the regulation of glutamine synthetase.

A higher activity of glutamine synthetase (EC 6.3.1.2) was found in Neurospora crassa when NH4+ was limiting as nitrogen source than when glutamate was limiting. When glutamate, glutamine or NH4+ were in excess, a lower activity was found. Immunol...

A large quantity of prepackaged mRNA is present in conidia of N. crassa as evidenced by its capacity to direct the synthesis of proteins in 2 heterologous cell-free systems. With this mRNA no in vitro synthesis of glutamine synthetase could be det...

The effect of the C and N source on the regulation of glutamine synthetase (GS) was studied by omitting 1 or both from mycelium which was grown in sucrose/glutamate medium, a condition in which GS is fully induced in its octameric form. The activi...
