Biosynthesis of Furanochromones
Canadian Journal of Biochemistry, 1971Radioactive khellin, visnagin, and visamminol were recovered from Ammi visnaga plants fed [1-14C]-acetate. A trapping experiment with 5,7-dihydroxy-2-methylchromone indicated that this compound was formed from acetate in the plant. It was then prepared labelled with 14C and 3H and administered to shoots, demonstrating its conversion to visamminol and ...

The biosynthesis of the purines
Ergebnisse der Physiologie Biologischen Chemie und Experimentellen Pharmakologie, 1959Of the many problems which confront the biologist in his understanding of the operations of the cell, the synthesis of biologically important substances is now the most amenable to solution. It has been the domain of the biochemist to probe into the integrated cellular system by dissembling its enzymatic machinery as a means of studying the complex ...

The formation of estrogens and phenolic material from a large number of do Cis, C19 and C2i steroids and related structures has been investigated, employing a human placental microsomal preparation supplemented with TPNH and oxygen. The data from the incubation of 2 C 14-labeled androgens are included.

The lignin biosynthetic pathway has been studied for more than a century but has undergone major revisions over the past decade. Significant progress has been made in cloning new genes by genetic and combined bioinformatics and biochemistry approaches.

No longer in-F-able: fluorine building blocks can be used in polyketide biosynthesis. This represents a more flexible approach to organofluorines than the traditional use of fluorinated starter units in multistep organic syntheses, and will hopefully increase the number of compounds available for drug development.

Alkaloid biosynthesis. Part XII. The biosynthesis of narcotine
Journal of the Chemical Society C: Organic, 1968Schemes for the degradation of narcotine (III) are devised which allow unambiguous isolation of labelled atoms from the alkaloid isolated from Papaver somniferum plants fed with a variety of precursors, both singly and multiply-labelled. It is shown in this way that the biosynthesis involves combination of two Ar–C–C units, derivable in the living ...

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.

This paper establishes the pathway for the biosynthesis of methanopterin in Methanosarcina thermophila to proceed by the following series of reactions. First, 5-phospho-alpha-D-ribosyl diphosphate (PRPP) and 4-aminobenzoic acid condense together to produce 4-(beta-D-ribofuranosyl)aminobenzene 5'-phosphate, which then reacts with 6-hydroxymethyl-7,8 ...
