Biotransformation 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...

MOLECULAR ANALYSIS OF THE SULFUR REGULATORY CIRCUIT OF NEUROSPORA CRASSA

The sulfur regulatory circuit of the filamentous fungus, Neurospora crassa, consists of a set of unlinked structural genes which encode sulfur catabolic and two major regulatory genes which govern their expression. The cys-3 regulatory gene encode a transacting regulatory protein which activates the expression of cys-14 and ars, whereas the other regulatory genes Scon-l and Scon-2 appear to...

Phospholipid Variations in Mutant Strains of Neurospora Crassa.

The present studies were undertaken to determine the extent to which the phospholipid composition of Neurosporn crama can be altered by mutations studied in conjunction with controlled supplementation. Previous work in this laboratory has shown that a mutation involving an enzyme concerned with lecithin synthesis can result in a lecithin-deficient strain (1, 2). The methylation of phosphatidyle...
