Catabolite Inactivation of Bakers'-Yeast Uridine Nucleosidase. Isolation and Partial Purification of a Specific Proteolytic Inactivase

European Journal of Biochemistry, 1977
When bakers' yeast cells are grown in culture media containing ethanol instead of glucose, uridine nucleosidase specific activity increased up to 10 times its original value. Addition of glucose to ethanol-grown cells caused a rapid drop of uridine nucleosidase activity.

Studies on tRNA Nucleotidyltransferase from Baker's Yeast

European Journal of Biochemistry, 1974
A rapid purification method for tRNA nucleotidyltransferase from baker's yeast has been worked out. The enzyme, purified 900‐fold with a yield of 20%, is electrophoretically pure.ATP and CTP protect the enzyme against heat inactivation and are competitive inhibitors for each other in the reaction of CCA attachment.

Reversible Inactivation of tRNA Nucleotidyltransferase from Baker's Yeast by tRNA^Phe Containing Iodoacetamide‐Alkylated 2‐Thiocytidine in Normal and Additional Positions

European Journal of Biochemistry, 1979
2‐Thiocytidine 5′‐triphosphate, s2CTP, is able to replace CTP as a substrate for tRNA nucleotidyltransferase. s2CMP can be incorporated into both cytidine sites of the C‐C‐A terminus common to all tRNAs, and in the absence of ATP into at least two additional positions. This was shown by alkylation of the 2‐thiocytidine residues with iodo[14C]acetamide,

Effect of Lower Fungi on Tacrolimus Biosynthesis (FK-506) by the Streptomyces tsukubensis VKM Ac-2618D Strain

Biotekhnologiya, 2019
The effect of inactivated yeast cells, cell components of yeast cells, and inactivated biomass of the lower fungi of various taxonomic positions on the immunosuppressant tacrolimus (FK-506) biosynthesis by Streptomyces tsukubensis VKM Ac-2618D has been ...

Investigation of drying and inactivation of bakers yeast in fluidized beds operated at reduced pressures

Wirbelschichttrocknungsprozesse werden zunehmend in der kommerziellen Produktion von granularen Feststoffen eingesetzt, da sie hohe Wärme- und Stoffübertragungsraten bieten. Bei der Verarbeitung von thermosensiblen Produkten in der Pharma- oder Lebensmittelindustrie kommt es häufig zu einer unerwünschten Inaktivierung oder einem thermischen Abbau von ...

A baker's yeast mutant (fil1) with a specific, partially inactivating mutation in adenylate cyclase maintains a high stress resistance during active fermentation and growth.

Journal of molecular microbiology and biotechnology, 2000
The initiation of fermentation in the yeast Saccharomyces cerevisiae is associated with a rapid drop in stress resistance. This is disadvantageous for several biotechnological applications, e.g. the preparation of freeze doughs. We have isolated mutants in a laboratory strain which are deficient in fermentation-induced loss of stress resistance ('fil ...
