Inhibition of lycopene cyclase results in accumulation of chlorophyll precursors.

abstract：:[1-(14)C]glycollate was oxidised to(14)CO2 by peroxisomes isolated from leaves of spinach beet about 3 times as rapidly at 35°C as at 25°C; the rate was further increased with rise in temperature to a maximum at 55°C. These increases are shown to be mainly due to the increased H2O2 available to oxidise glyoxylate non-...
