The subunit structure of tryptophan synthase from Neurospora crassa.
Tryptophan synthase of Neurospora crassa was purified to electrophoretic homogeneity from the wild type strain 74A which had been derepressed by the presence of 0.5 mM indoleacrylic acid in the growth medium. The isolated material migrated as a single symmetrical peak in the ultracentrifuge with a sedimentation constant of 6.0 S. Gel filtration on Sephadex G-200 AND CONVENTIONAL SEDIMENTATION E...

Tryptophan synthase of Neurospora crassa was purified to electrophoretic homogeneity from the wild type strain 74A which had been derepressed by the presence of 0.5 rnr,r indoleacrylic acid in the growth medium. The isolated material migrated as a single symmetrical peak in the ultracentrifuge with a sedimentation constant of 6.0 S. Gel filtration on Sephadex G-ZOO and conventional sedimentatio...
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 کاملProperties of chorismate synthase in Neurospora crassa.
Chorismate synthase was isolated from Neurospora crassa by diethylaminoethylcellulose chromatography, and two peaks of activity were obtained. The enzyme in the first peak had a sedimentation coefficient of ~10 S and appeared to be an unstable, larger molecular form of the enzyme in the second peak, which was -8 S. Both forms of the enzyme required TPNH for activity, and the reactions catalyzed...
