Store lyophilized/reconstituted at -20°C; once reconstituted make aliquots to avoid repeated freeze-thaw cycles. Please, remember to spin tubes briefly prior to opening them to avoid any losses that might occur from lyophilized material adhering to the cap or sides of the tubes.
For reconstitution add 50 µL of sterile water.
Specific Species Reactivity: Nicotiana tabacum
PetL is a plastid-encoded gene in photosynthetic organisms whose product is a very small, highly hydrophobic membrane protein that localizes to the chloroplast thylakoid membrane as an accessory component of the cytochrome b6f complex. In higher plants, PetL is an approximately 31-amino-acid polypeptide predicted to form a single transmembrane helix, with evidence suggesting its N-terminus faces the thylakoid lumen, consistent with its role as one of the "small subunits" embedded in the b6f dimer. Functionally, PetL is not strictly required for initial cytochrome b6f accumulation or photosynthetic electron transport capacity in young tissue; however, genetic disruption studies show that loss of PetL compromises cytochrome b6f complex stability, leading to accelerated, leaf age-dependent depletion of the complex and reduced photosynthetic performance in mature/older leaves, indicating a specific role in maintaining long-term structural integrity and/or resistance to destabilizing conditions rather than serving as a catalytic electron-transfer subunit.
