Pyridine Nucleotide Cycle

Trigonelline is synthesized from nicotinic acid in many plant species. This compound accumulates in seeds of leguminous plants and Coffea sp. The present article reviews the distribution of nicotinic acid conjugates and biosynthetic pathways of trigonelline, including the pyridine nucleotide cycle and de novo synthesis. The function of trigonelline in plants is also discussed.

Abstract Application of [6-14C]-or [7-14C]nicotinic acid to parsley cell suspension cultures led to the accumulation of labelled nicotinamide mononucleotide, nicotinamide adenine dinucleotide, nicotinamide N-riboside, nicotinamide and nicotinic acid, indicating the operation of the pyridine nucleotide cycle in these cells. As main conjugates, nicotinic acid N-glucoside and nicotinic acid glucose ester were found. For nicotinic acid degradation the following sequence is suggested: nicotinic acid → 6-hydroxynicotinic acid → 2,5-dihydroxypyridine → a C4/C3 unit of unknown structure → CO2. In aseptically grown parsley seedlings nicotinic acid is also degraded to CO2
