Plastoquinone

(Synonyms: PQ-9)

Plastoquinone (PQ-9) is a photosynthetic electron carrier as well as a redox sensor capable of regulating state transitions and gene expression. Plastoquinone transfers electrons to the cytochrome b₆/f complex via the Q cycle, and participates in the establishment of the thylakoid transmembrane pH gradient. Plastoquinone can react with ROS. Plastoquinone is used in plant photosynthesis research.

Biological Activity

Description

In Vitro

Plastoquinone is an essential component of photosynthesis that carries
electrons in the linear and alternative electron transport chains, and is also a
redox sensor that regulates state transitions and gene expression^[1].
Plastoquinone is involved both in
intersystem electron flow and in the establishment of the transthylakoidal pH gradient^[1].
Plastoquinone has been viewed as a photosynthetic electron carrier, shuttling electrons from PSII to cytochrome b6/f^[1].
Plastoquinone is capable of membrane diffusion and can therefore react with ROS in various photosynthetic electron transport chain regions where ROS are generated^[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
