The Utilization of Pyruvic Acid by Bakers’ Yeast*
If sodium pyruvate is added to cells of bakers’ yeast suspended in a phosphate buffer of pH 7.0 in the strict absence of oxygen, practically no pyruvate is utilized. After 3 hours in contact with the cells the sodium pyruvate can be almost quantitatively recovered. If, however, oxygen is admiNed to the cells, then both pyruvate and oxygen are utilized at appreciable rates (see Table I). So far ...
متن کاملTHE 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...
