The biosynthesis of the purines [PDF]
Ergebnisse der Physiologie Biologischen Chemie und Experimentellen Pharmakologie, 1959 Of 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 ...

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 ...

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 ...

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 rove beetles of the genus Stenus Latreille synthesize the alkaloid stenusine in their pygidial glands, which are located in the last three segments of their abdomen. It is proposed that stenusine is derived from the two amino acids, L-lysine and L-isoleucine. Feeding S. bimaculatus beetles with deuterium-labeled amino acids and using GC/MS analysis
