Isolation and characterization of the tyrosinase gene from Neurospora crassa.
A precursor form of Neurospora crassa tyrosinase has been identified by Western transfer from crude protein extracts and by immunoprecipitation of in vitro translated tyrosinase mRNA. The molecular weight of protyrosinase (75,000) exceeds that of mature tyrosinase (46,000) by about 50%. In order to deduce the primary structure and the nature of the extension, the tyrosinase gene was cloned. Pol...
متن کاملComparison of amino acid sequence and thermostability of tyrosinase from three wild type strains of Neurospora crassa.
The thermostability of tyrosinase from three wild type strains of Neurospora crassa has been investigated. For this purpose a sequence comparison of two thermostable and one thermolabile tyrosinase isoenzyme was carried out. It revealed that at position 201 the thermostable enzyme forms share an aspartate residue in contrast to an asparagine residue in the thermolabile form. In addition, one of...
متن کاملAmino acid sequence of tyrosinase from Neurospora crassa.
The amino-acid sequence of tyrosinase from Neurospora crassa (monophenol,dihydroxyphenylalanine:oxygen oxidoreductase, EC 1.14.18.1) is reported. This copper-containing oxidase consists of a single polypeptide chain of 407 amino acids. The primary structure was determined by automated and manual sequence analysis on fragments produced by cleavage with cyanogen bromide and on peptides obtained b...
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...
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...
