#Unit 1. Structure and Function of Biomolecules

Eukaryotic cells have two isozymes of aconitase
• The mitochondrial isozyme (convert citrate to isocitrate in the citric acid cycle)
• The cytosolic isozyme

#Unit 1. Structure and Function of Biomolecules

The cytosolic isozymes has two distinct function, It catalyzes the conversion of citrate to isocitrate, providing the substrate for a cytosolic isocitrate dehydrogenase that generates NADPH as reducing power for fatty acid synthesis and other anabolic processes in the cytosol. It also has a role in cellular iron homeostasis

When cellular iron concentrations return to normal levels, IRP1 is converted to aconitase, and IRP2 undergoes proteolytic degradation, ending the low-iron response.

#Unit 1. Structure and Function of Biomolecules

Pyruvate kinase acts in the nucleus to regulate the transcription of genes that respond to thyroid hormone. Glyceraldehyde 3-phosphate dehydrogenase moonlights both as uracil DNA glycosylase, effecting the repair of damaged DNA, and as a regulator of histone H2B transcription.
