Positional 13C Enrichment Analysis of Aspartate by GC-MS to Determine PEPC Activity In Vivo

Luisa Wittemeier, Yogeswari Rajarathinam, Alexander Erban, Martin Hagemann, Joachim Kopka

This paper develops a GC-MS-based method to measure PEPC activity in vivo by analyzing positional 13C enrichment in aspartate from Synechocystis cultures.

In vivo RUBISCO activity in Synechocystis is regulated by RuBP availability

Luisa Wittemeier, Stéphanie Arrivault, Niels Neumann, Boris Maček, Nils Schmidt, Martin Hagemann, Joachim Kopka

This study shows that RUBISCO activity in Synechocystis is regulated by RuBP availability, with CP12 inactivating the CBB cycle during darkness and affecting RuBP levels.

Dynamic photosynthetic labelling and carbon-positional mass spectrometry monitor in vivo carbon assimilation rates by ribulose-1,5-bisphosphate carboxylase.

Yogeswari Rajarathinam, Luisa Wittemeier, Kirstin Gutekunst, Martin Hagemann, Joachim Kopka

This paper develops a method to distinguish RUBISCO activity from CBB cycle activities by analyzing carbon positional labeling in 3PGA using GC-MS after 13CO2 labeling.
