Anti-PsbE | Alfa subunit of Cytochrome b559 of PSII

Cytochrome b559 (Cyt b559) is encoded by the chloroplast genes psbE and psbF and is comprised of two low molecular mass polypeptides, a and h subunits, with molecular masses of 9 and 4 kDa, respectively. The Cyt b559 is closely associated with PSII in all oxygenic photosynthetic organisms. The a and h subunits of the Cyt b559 are components of the minimal PSII reaction center complex that is still capable of primary charge separation In summary, both PsbE and PsbF are essential components for PSII assembly, and they are probably involved in electron transport mechanisms that help to protect PSII from photodamage. Alternative protein name: PSII reaction center subunit V

Store lyophilized/reconstituted at -20°C; once reconstituted make aliquots to avoid repeated freeze-thaw cycles. Please remember to spin the tubes briefly prior to opening them to avoid any losses that might occur from material adhering to the cap or sides of the tube.
