The glyoxylate cycle is essential for growth on C2 compounds such as acetate. In this investigation, for the first time, we have elucidated the subcellular localization of the enzymes of the glyoxylate cycle in the green microalga Chlamydomonas reinhardtii. Acetyl-CoA synthase and malate dehydrogenase exist as multiple isoforms in this microalga, therefore, we first identified those implicated in the glyoxylate cycle based on the observation that lack of isocitrate lyase (ICL) in a previously identified icl deficient mutant was correlated with specific loss of the other enzymes of the glyoxylate cycle. In this work, we determined that five of the six enzymes associated with the glyoxylate cycle were found to be within peroxisomal microbodies. Citrate synthase, aconitase, malate synthase, malate dehydrogenase, and acetyl-CoA synthase are located in peroxisomal microbodies while isocitrate lyase is cytosolic. Our findings implicate a key role for these cellular compartments in acetate assimilation for Chlamydomonas. Microbodies have only recently been discovered in C. reinhardtii and their existence had been previously debated. The isoform specific subcellular localization determined here suggests that peroxisomal microbodies should be considered in the design of metabolic models for carbon assimilation in C. reinhardtii.
