摘要: Introduction Heme consists of a protoporphyrin ring with tightly bound iron atom, which can exist in both ferrous (Fe2+) and ferric (Fe3+) state, held the centre molecule by four nitrogen atoms. This is fundamental importance many biochemical pathways including oxygen transport hemoglobin electron respiratory chain. also prosthetic group for numerous enzymes, most notably context this book include cyclooxygenase (COX) nitric oxide synthesis (NOS) [1]. has been demonstrated to regulate protein synthase via elf-2a kinase [2]. Therefore, maintenance heme pool considerable eukaryotic systems, levels intracellular being controlled at level biosynthesis degradation.
