Since Phe-tRNA synthetase of Neurospora crassa reacts with tRNAV”’ of Escherichia coli to produce Phe-tRNAV&‘, the parameters that effect the reverse reaction were examined. Similarly, the interaction of Val-tRNA synthetase (E. coti) with Phe-tRNAVal and Val-tRNAVal (E. coli) was studied. Phe-tRNA synthetase (N. crassa) can catalyze the deacylation of both Phe-tRNAVa 1 (E. coli) and Val-tRNAV”’...

Calcineurin is a calcium/calmodulin dependent protein phosphatase in eukaryotes that consists of a catalytic subunit A and a regulatory subunit B. Previous studies in the filamentous fungus Neurospora crassa had suggested that the catalytic subunit of calcineurin might be an essential protein. We generated N. crassa strains expressing the A (cna-1) and B (cnb-1) subunit genes under the regulati...

The precursor relationship of cystathionine in the biosynthesis of methionine by Neurospora crassa was first indicated by Horowitz (1947). Isotope competition studies with N. crassa yielded evidence that the sulfur of cystathionine can supply a large portion of the sulfur needed for growth (Roberts et al., 1955). Isolation of the cystathionine-cleaving enzymes and their respective reaction prod...

Transcription factors (TFs) are key nodes of regulatory networks in eukaryotic organisms, including filamentous fungi such as Neurospora crassa. The 178 predicted DNA-binding TFs in N. crassa are distributed primarily among six gene families, which represent an ancient expansion in filamentous ascomycete genomes; 98 TF genes show detectable expression levels during vegetative growth of N. crass...

Heterologous expression of plant genes may serve as an important alternative for producing plant proteins. We have investigated the ability of the fungus Neurospora crassa to secrete zeamatin, a protein produced by Zea mays. Zeamatin was induced after being fused to glucoamylase, an extracellular hydrolase produced by N. crassa. Glucoamylase induction and other culture parameters were monitored...
