Comparative quantitative proteomics to investigate the remodeling of bioenergetic pathways under iron deficiency inChlamydomonas reinhardtii (original) (raw)

This study examines the adjustments in energy metabolism of Chlamydomonas reinhardtii due to iron deficiency, employing comparative quantitative proteomics alongside spectroscopic and voltametric oxygen measurements. Key findings indicate that, despite a compromised photosynthetic electron transport under low iron conditions, the functional size of photosystem II (PSII) increases and certain stress-related polypeptides are induced. Additionally, respiratory oxygen consumption remains stable, suggesting a metabolic shift towards heterotrophic pathways that illustrates a selective iron allocation within organelles based on cellular metabolic states.
