IT is the purpose of the present communication to describe some further results with carbon-14 precursors of ethylene, and to reconcile the pattern which emerges in these investigations using McIntosh apple tissue sections with that of the fungal system, Penicillium digitatum.

The Biosynthesis of Deoxyribonucleotides
2004Ribonucleotide reductases play a central role in DNA biosynthesis. They catalyze the conversion of NDPs (NTPs) to dNDPs (dNTPs) concomitant with oxidation of thiols within their active sites. A single active site can accomodate reduction of both purine and pyrimidine nucleotides.

AbstractInformation has recently been obtained, mainly with the aid of radioactive compounds, about the biosynthesis of various cyclitols. It was found that the most widely occurring cyclitol, meso‐inositol, is biosynthesized by a pathway probably common to all organisms, in which the cyclohexane ring is formed by ring closure between the two terminal ...

During the late 1930s, Barker isolated an anaerobic bacterium which he called Clostridium kluyveri. This organism is able to grow on a mixture of acetate and ethanol and produces n-butyrate and n-caproate. From this organism, Barker and Stadtman obtained cell-free extracts which could carry the reactions leading to the C4 and C6 acids.

Abstract The radioactive carbon atom of sodium acetate - 2-C 14 injected into the body cavity of honey bees actively synthesizing wax was incorporated into the free acids and esters of the wax within a few hours. The specific activity of the wax was 5000 c.p.m.
