DNA 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 کاملPre-employment screening among trainee bakers.
OBJECTIVES To assess the prevalence of atopy in a vocational school so as to evaluate the feasibility of pre-employment screening. METHODS The prevalence of atopy by family diathesis, prick tests, immunoglobulin E (IgE) concentrations, and personal history of allergic respiratory diseases was investigated in 144 trainee bakers and 81 students on a graphic artists course (mean age 15.4 years)....
متن کاملCytoplasmic Methionyl - tRNA Synthetase from Bakers ’ Yeast
Methionyl-tRNA synthetase has been purified from a yeast strain carrying the MESl structural gene on a high copy number plasmid (pFL1). The purified enzyme is a monomer of M, = 85,000 in contrast to its counterpart from Escherichia coli which is a dimer made up of identical subunits (M, = 76,000; Dardel, F., Fayat, G., and Blanquet, S . (1984) J. Bucteriol. 160,1115-1122). The yeast enzyme was ...
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 ...
