چکیده

A phosphatase, active towards phosphorylase a and phosphorylated proteins casein and histone II-A, was isolated from Saccharomyces cerevisiae 257. The enzyme dephosphorylated glycogen phosphorylase from commercial yeast rendering it inactive. The protein phosphatase activity was not influenced by any metal ions. Phosphorylase phosphatase activity was slightly stimulated by p-nitrophenyl phosphate and inhibited by heparin.

Purification and Properties of Alkaline Phosphatase with Protein Phosphatase Activity from Saccharomyces cerevisiae

An alkaline phosphatase (A LPase) from Saccharomyces cerevisiae strain 257 was purified 345-fold with specific activity of 54 533 nmol x min“ 1 x mg protein-1 . It was shown to be a dimeric protein (apparent mol. wt. approx. 130 kDa) with optimum activity at pH 8.6 8.8 and good stability at 50 °C. The A LPase was a non-specific enzyme hydrolyzing a wide vari­ ety of monophosphate esters. The en...

Yeast permeabilization as a tool for measurement of in situ enzyme activity: localization of alkaline phosphatase.

The biochemical and ultracytochemical localization of alkaline phosphatases in permeabilized cells of Saccharomyces cerevisiae 257 has been studied. The treatment with non-ionic surfactant Triton X-100 allows the penetration of the substrate into intact yeast cells and thus provides detailed detection of the enzyme activity in ultracytochemical studies.

Effect of dietary supplementation with zinc enriched yeast (Saccharomyces cerevisiae) on immunity of rainbow trout (Oncorhynchus mykiss)

Zinc (Zn) is an essential trace element in all living organisms, and the first eukaryotic Zn uptake transporter was discovered in the yeast, Saccharomyces cerevisiae. Zinc-enriched yeast is a currently available Zn supplement. The purpose of the investigation was to compare and evaluate the effect of Zn enriched yeast in rainbow trout. The fish (mean body weight 10 ± 0.5 g) were fed a commercia...
