Cytochrome b5: novel roles in steroidogenesis.
Stellenbosch, South Africa. In Mol Cell Endocrinol, 2013
Cytochrome b(5) (cyt-b(5)) is essential for the regulation of steroidogenesis and as such has been implicated in a number of clinical conditions.
Intestinal iron absorption.
Brisbane, Australia. In J Trace Elem Med Biol, 2012
Most of this iron is moved across the enterocyte brush border membrane by the iron transporter divalent metal-ion transporter 1, a process enhanced by the prior reduction of the iron by duodenal cytochrome B and possibly other reductases.
Cytochrome b₅₅₉ and cyclic electron transfer within photosystem II.
New Haven, United States. In Biochim Biophys Acta, 2012
Cytochrome b₅₅₉ (Cyt b₅₅₉), β-carotene (Car), and chlorophyll (Chl) cofactors participate in the secondary electron-transfer pathways in photosystem II (PSII), which are believed to protect PSII from photodamage under conditions in which the primary electron-donation pathway leading to water oxidation is inhibited.
