Interaction of the Neurospora crassa heat shock factor with the heat shock element during heat shock and different developmental stages.
The interaction of the heat shock factor (HSF) with the heat shock element (HSE) was determined by a non-radioactive electrophoretic mobility shift assay, in order to analyze HSF regulation in Neurospora crassa. HSF binds to HSE under normal, non-stress conditions and is thus constitutively trimerized. Upon heat shock, the HSF-HSE complex shows a retarded mobility. This was also observed in Sac...

15 صفحه اولGenetic Mechanisms Governing the Effect of Canavanine on Neurospora Crassa.
OROWITZ and SRB (1948) first noted that wild type strains of Neurospora H crassa may be sensitive to the amino acid canavanine. They reported three types: one sensitive, one resistant, and one of intermediate sensitivity. TEAS (1951) studied two mutant homoserine-requiring strains, 46003-R (canavanine resistant) and 460033 (sensitive). He found that canavanine sensitivity is heritable and indep...
متن کاملMechanisms of protection of trehalase against heat inactivation in Neurospora.
The half-life of trehalase and invertase at 65 and 60 C was found to be much greater when intact ascospores of Neurospora tetrasperma were heated, as compared with extracts. By contrast, no protection was afforded these enzymes when they were heated in intact conidia and mycelium of N. crassa or N. tetrasperma. The protective effect of ascospores for trehalase was further investigated by heatin...
متن کاملBiotransformation of Hydrocortisone by Neurospora crassa
The ability of Neurospora crassa FGSC 4335 in the biotransformation of hydrocortisone was investigated. The microorganism produced two major metabolites after incubation with the substrate for seven days. Each microbial product was purified chromatographically and identified on the basis of spectral data. The products were identified as 11?,17?,20?,21-tetrahydroxypregn-4-en-3-one (II) and 11?-h...
