Contracting nucleolar vacuoles in somatic tobacco cells growing in microcultures

Creator:: Johnson, John Morris
Abstract:: Contracting nucleolar vacuoles are a general and consistent feature of somatic tobacco cells growing in microcultures. Nucleolar vacuoles were studied in cells from callus tissues of two single-cell clones, H-196 and H-239, of hybrid tobacco (Nicotiana tabacum X N. glutinosa). Vacuoles periodically contracted either completely or incompletely, apparently releasing a...

Terminal methylation reactions in Saccharomyces cerevisiae

Creator:: Botsford, James Lawrence
Abstract:: A cell-free system for assessing the role of S-adenosyl-methionine in the methylation of homocysteine deriving the methyl group from serine has been developed. No role for S-adenosyl-methionine could be shown in the in vitro reaction The enzyme serine transhydroxymethylase has been studied in crude and partially purified cell extracts. Evidence...

Phytochemical investigation of Arctostaphylos columbiana Piper and Arctostaphylos patula Greene

Creator:: Constantine, George Harmon
Abstract:: There are numerous references in the literature concerning the use of various Arctostaphylos species as medicinal plants. One of the species, A. uva-ursi, was listed in the United States official compendia from 1820 until 1946 as a urinary antiseptic. Many species indigenous to the Pacific Northwest were employed by the...

The role of S-adenosylmethionine in the biosynthesis of ergosterol and related sterols in Saccharomyces cerevisiae

Creator:: Turner, Jan Ross
Abstract:: An enzyme system was prepared from Saccharomyces cerevisiae, strain MCC, which carries out the transfer of the methyl group from S-adenosylmethionine or methionine to the side chain of yeast sterols. The cell-free system has been shown to be incapable of synthesizing ergosterol but carries out the synthesis of two as...

Some properties of ribonucleotide reductase in Rhizobium species

Creator:: Cowles, Joe Richard, 1941-
Abstract:: Ribonucleotide reductase from Rhizobium meliloti has been partially purified and characterized. The enzymatic reduction of ribonucleotides to deoxyribonucleotides is dependent upon B₁₂ coenzyme and dihydrolipoate. B₁₂ coenzyme was more effective than B₁₂ coenzyme analogues in the reductase reaction. The affinity of the R. meliloti reductase system for B₁₂ coenzyme was...
