Distribution of folates and modified folates in extremely thermophilic bacteria.

Author(s) : White, R H
Description : Analyses were made of the structures and levels of folates and modified folates present in extremely thermophilic bacteria. These procedures involved the chemical analysis of products resulting from the oxidative cleavage of the 6-substituted, folatelike tetrahydropterins present in the cells. Air-o...

Structural diversity among methanofurans from different methanogenic bacteria.

Author(s) : White, R H
Description : An examination of the methanofurans isolated from a wide range of methanogenic bacteria and from Archaeoglobus fulgidus has revealed at least five chromatographically distinct methanofurans. Bacteria from each major genus of methanogenic bacteria have been found to contain a chemically different met...

Structures of the modified folates in the extremely thermophilic archaebacterium Thermococcus litoralis.

Author(s) : White, R H
Description : The chemical structures of the two modified folates present in Thermococcus litoralis were established. These compounds, each containing a core structure of 1-[4-[[1-(2-amino-7-methyl- 4-oxo-6-pteridinyl)-ethyl]amino]phenyl]-1-deoxy-[1-alpha-D- ribofuranosyl]-ribitol, were characterized. The five po...

Analysis and characterization of the folates in the nonmethanogenic archaebacteria.

Author(s) : White, R H
Description : A detailed analysis of the folate coenzymes in the nonmethanogenic archaebacteria has been performed. By using the Lactobacillus casei microbiological assay for folates, the levels of folates in Sulfolobus solfataricus and Sulfolobus acidocaldarius were found to be 3.7 and 8.3 ng/g (dry weight) of c...

Indole-3-acetic acid and 2-(indol-3-ylmethyl)indol-3-yl acetic acid in the thermophilic archaebacterium Sulfolobus acidocaldarius.

Author(s) : White, R H
Description : Indole-3-acetic acid (IAA) and 2-(indol-3-ylmethyl)indol-3-yl acetic acid were identified in lipid extracts of Sulfolobus acidocaldarius; they occurred at concentrations of 0.57 and 0.59 mumol/g (dry weight), respectively. The amount of IAA found in these cells is more than a thousand times greater ...

Biosynthesis of the 7-methylated pterin of methanopterin.

Author(s) : White, R H
Description : The incorporation of [15N]glycine and [U-methyl-2H]methionine into methanopterin by growing cells of a methanogenic bacterium was measured to establish the biosynthetic route of the methylated pterin in the structure. The tetrahydromethanopterin produced by the cells was oxidatively cleaved to produ...

Biosynthesis of the sulfonolipid 2-amino-3-hydroxy-15-methylhexadecane-1-sulfonic acid in the gliding bacterium Cytophaga johnsonae.

Author(s) : White, R H
Description : The biosynthesis of the sulfonolipid 2-amino-3-hydroxy-15-methylhexadecane-1-sulfonic acid (capnine) was studied by measuring the incorporation of possible precursors into the lipid by cells grown in the presence of precursors which were labeled with stable isotopes. Cells grown on yeast extract in ...

7-Methylpterin and 7-methyllumizine: oxidative degradation products of 7-methyl-substituted pteridines in methanogenic bacteria.

Author(s) : White, R H
Description : 7-Methylpterin and 7-methyllumizine were isolated and identified in extracts of methanogenic bacteria which had been extracted in air with ethanol-water. Ethanol-water preparations of cells extracted under nitrogen or hydrogen were devoid of these compounds. Extracts of cells obtained in the presenc...
