THE CALCIUM BINDING SITES OF THE BAKERS' YEAST TRANSKETOLASE
The calcium binding sites of Bakers' Yeast Transketolase (TK) was elucidated by estimating the pKa values of the functional groups that bind to calcium. These pKa's were found to be 6.25 and 7.2 relating to the pKa's of the two immidazol moieties of histidine residues on the enzyme. The rate of the binding of calcium to the enzyme was obtained separately as a function of pH. Maximum values ...
متن کاملDNA polymerases from bakers' yeast.
Two DNA polymerases are present in extracts of commercial bakers' yeast and wild type Saccharomyces cerevisiae grown aerobically to late log phase. Yeast DNA polymerase I and yeast DNA polymerase II can be separated by DEAE-cellulose, hydroxylapatite, and denatured DNA-cellulose chromatography from the postmitochondrial supernatants of yeast lysates. The yeast polymerases are both of high molec...
متن کاملFormaldehyde dehydrogenase from bakers' yeast.
In the course of studies of formaldehyde metabolism in yeast (I), an enzyme was found that catalyzed the oxidation of formaldehyde in the presence of glutathione and diphosphopyridine nucleotide. A similar enzyme was discovered independently by Strittmatter and Ball in liver (2). This paper describes the partial purification and some of the properties of yeast formaldehyde dehydrogenase. Some e...
متن کاملPurification and Properties of Bakers' Yeast Trehalase.
Since recent surveys of insect hemolymph (1, 2) have shown that trehalose is the major blood sugar, the hydrolytic enzyme trehalase has also awakened the interest of investigators. A purified preparation of the enzyme from Galleria mellonella (3) and from Phormia regina (4) was recently obtained and some of its properties described. The biosynthesis of trehalose with an enzyme preparation from ...
متن کاملProducing aglycons of ginsenosides in bakers' yeast
Ginsenosides are the primary bioactive components of ginseng, which is a popular medicinal plant that exhibits diverse pharmacological activities. Protopanaxadiol, protopanaxatriol and oleanolic acid are three basic aglycons of ginsenosides. Producing aglycons of ginsenosides in Saccharomyces cerevisiae was realized in this work and provides an alternative route compared to traditional extracti...
