WebThe heme-transport genes are often genetically linked as gene clusters under Fur (ferric uptake regulator) regulation. This review discusses the gene clusters and proteins involved in bacterial heme acquisition, transport and processing processes, with special focus on the heme-coordination, protein structures and mechanisms underlying heme-transport. Cytochrome c is an essential component of the respiratory electron transport chain in mitochondria. The heme group of cytochrome c accepts electrons from the bc1 Complex III and transports them to Complex IV, while it transfers energy in the opposite direction. Cytochrome c can also catalyze several redox reactions such as hydroxylation cabaniss show lambs caban jacke wolle
