WebElectron Transport System. The electron transport system occurs in the cristae of the mitochondria, where a series of cytochromes (enzymes) and coenzymes exist. These cytochromes and coenzymes act as carrier molecules and transfer molecules. They accept high-energy electrons and pass the electrons to the next molecule in the system. WebIn plants and cyanobacteria, cytochrome b6 consists of two protein subunits encoded by the petB and petD genes. Cytochrome b/b6 non-covalently binds two heme groups, known as b562 and b566.

WebThe cytochrome b6f complex is an integral membrane protein complex which catalyzes electron transfer from plastoquinol to plastocyanin and pumps protons across the thylakoid membrane. Its turnover rate in chloroplasts can be up to 300 s −1 (reviewed in Hauska et al., 1983; Hope, 1993; Cramer et al., 1994 ). Webcrops. Some essential P450 functions are conserved among plant species1,2, including hormone, sterol and oxygenated fatty acid synthesis. Others, probably the majority, are involved in aspects of secondary metabolism that differ from plant to plant. Conse-quently, P450 number and substrate specificity also differs from plant to plant.

Cytochromes are redox-active proteins containing a heme, with a central iron (Fe) atom at its core, as a cofactor. They are involved in electron transport chain and redox catalysis.
