Web25 jun. 2024 · Figure 2. The possible interconnected pathways for the movements of heme in cells, and the links to signaling gases such as CO and NO. From the total heme synthesized in the cell (top), a proportion is bound irreversibly to heme-binding housekeeping proteins (red circles) that are essential for cell survival. WebHeme signaling. Extracellular hemoglobin, a byproduct of hemolysis, can release its prosthetic heme groups upon oxidation. Blood plasma contains proteins that scavenge heme. It is estimated that about 2–8% of the heme released in plasma becomes ‘bioavailable’, being internalized by bystander cells. If the heme degradation capacity of a ...

The pathway is initiated by the synthesis of δ-aminolevulinic acid (dALA or δALA) from the amino acid glycine and succinyl-CoA from the citric acid cycle (Krebs cycle). The rate-limiting enzyme responsible for this reaction, ALA synthase, is negatively regulated by glucose and heme concentration.
