regulation of early reactions in the biosynthesis of tryptophan in neurospora crassa.lester, gabriel (reed college, portland, ore.). regulation of early reactions in the biosynthesis of tryptophan in neurospora crassa. j. bacteriol. 85:468-475. 1963.-the regulation of the biosynthesis of tryptophan was examined in neurospora crassa, strain ylo-tryp-la, which accumulates anthranil compounds. the block in this strain appeared to be in the conversion of 1-(o-carboxyphenylamino)-1-deoxyribulose-5-phosphate to indole-3-glycerol phosphate, since the dephosphorylated form of the former ...196313929917

characterization of ribosomes from neurospora crassa.ribosomes isolated from growing hyphae of neurospora crassa contain 53 per cent protein and 47 per cent rna and have a sedimentation coefficient of 81s at 20 degrees c and infinite dilution. these ribosomes are stable at ph 7.4 in the presence of 0.01 m and 0.002 m mgcl(2) but undergo a dissociation into smaller particles if the mgcl(2) concentration is lowered to 0.0001 m. two types of rna with sedimentation coefficients of 19s(20) (50) and 13s(20) (50) have been extracted from the 81s particle ...196313984420

studies on a cytoplasmic character in neurospora crassa.two morphologically distinctive slow growing strains of neurospora crassa have been isolated and studied. these, abn-1 and abn-2, differ from wild type in that their growth rates are greatly reduced and often irregular, aerial hyphae are absent, conidia are extremely rare, and no protoperithecia are formed. growth was not improved by addition of any nutrients tested, oxygen consumption was similar to that of wild type, and cytochrome c appeared abnormally high, and b low or absent. both abn stra ...19655865932
