Eickenbusch, JD; Scheibe, R; Beck, E: Active glycolaldehyde and ribulose diphosphate as carbon sources for oxidative glycolate formation, Zeitschrift für Pflanzenphysiologie, 75, 375-380 (1975), doi:10.1016/S0044-328X(75)80104-8
Abstract:
A direct comparison of carbon incorporation from various possible precursors (see Table 1) into glycolate was made with a reconstituted chloroplast system. Oxidative glycolate formation at love O2 concentrations was most efficient with fructose 6-phosphate and ribulose 1,5-bisphosphate as substrates. At high O2 concentration, glycolate synthesis from fructose 6-phosphate remained unchanged; whereas that from ribulose 1,5-bisphosphate almost doubled. This suggests that different carbon sources were used by the 2 types of Oxidative glycolate formation described earlier (Eickenbusch and Beck, 1973). Activated glycol aldehyde originating from the transketolase reaction from fructose 6-phosphate is assumed to be the substrate in the O2 independent reaction; whereas the carbon source for the oxygen dependent one is ribulose 1,5-bisphosphate.
