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...
متن کاملMOLECULAR 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...
متن کاملRed Cell Diphosphoglycerate Mutase
Diphosphoglycerate mutase (DPGM) was purified to homogeneity from human erythrocytes. The enzyme and Freund adjuvant were infected into chickens and yielded a monospecific precipitating antibody. Radial immunodiffusion with this antibody was used to measure the amount of DPGM in hemolysates from human adult and cord red cells. Dog, rabbit, rat, chicken, and goat red cells all had DPGM during th...
متن کاملConformational flexibility of PEP mutase.
Previous work has indicated that PEP mutase catalyzes the rearrangement of phosphoenolpyruvate to phosphonopyruvate by a dissociative mechanism. The crystal structure of the mutase with Mg(II) and sulfopyruvate (a phosphonopyruvate analogue) bound showed that the substrate is anchored to the active site by the Mg(II), and shielded from solvent by a large loop (residues 115-133). Here, the cryst...
متن کاملDistribution of two types of phosphoglyceric acid mutase, diphosphoglycerate mutase, and D-2,3-diphosphoglyceric acid.
the difference between the two types being in their requirement for 2,3-DPGA. Reactions 1 and 2 have been studied recently with crystalline and highly purified enzyme preparations (3-5). For clarity, in this paper the enzymes catalyzing these reactions are called 2,3DPGA dependent mutase and 2,3-DPGA independent mutase. We observed previously that the phosphoglyceric acid mu&se from several tis...
