Purification of the Internal Invertase of Yeast*
Most of the studies on yeast invertase have been concerned only with the external enzyme (a mannan protein which is localized in the cell wall), but recently it has been reported that the invertase inside the cytoplasmic membrane is a smaller form. This paper presents a comparative study of the distribution of invertase isozymes in two stains of yeast and, after the selection of the best condit...

متن کاملCholine Kinase from Brewers’ Yeast
Choline kinase was purified approximately 300-fold, in 5% yield, from an autolysate of dried brewers’ yeast. A molecular weight of 67,000 was estimated using a Stokes radius of 33 A, as determined by Sephadex G-200 chromatography. An s~,,,~ of 4.8 S was obtained by sucrose density gradient centrifugation. Enzyme activity was diminished by sulfhydryl inhibitors and stabilized by the presence of ...
متن کاملComparative properties of amplified external and internal invertase from the yeast SUC2 gene.
Saccharomyces cerevisiae external and internal invertases have been amplified by introducing the normal and modified SUC2 genes into yeast multicopy plasmids, which were then used to transform a yeast strain resistant to repression by glucose. Amino acid compositional analysis of these enzymes, in addition to end group sequencing, confirmed the DNA sequence data of Taussig and Carlson (Taussig,...
