The first gene, psbC encodes CP43 protein which connects with the CP47 encoded by psbB. Along with the CP47, psbC form a proximal antennae. This conducts electron excitation from the external antennae to the PSII core reaction centre [1]. Due to results from deletion studies, the role of the CP43/psbC protein has been described as non-essential for the PSII core assembly [2].

The second gene in this part, psbA, encodes the D1 subunit of PSII. Along with the psbD which encodes the D2 subunit, it forms a heterodimer. This forms the PSII reaction centre [4] which is responsible for electron transfer from chlorophyll P680 to quinones QA and QB. It is also vital to the assembly of the oxygen evolving complex and QB within PSII [5].

Overview

This part is made up of psbC and psbA. The psbC gene that comprises this part codes a subunit that makes up the Photosystem II protein P680. The P680 complex is photosystem II primary electron donor. The psbA gene that comprises this part encodes the D2 protein, which is one of the two proteins that comprise the Photosystem II reaction center core.

The first gene, psbC encodes CP43 protein which connects with the CP47 encoded by psbB. Along with the CP47, psbC form a proximal antennae. This conducts electron excitation from the external antennae to the PSII core reaction centre [1]. Due to results from deletion studies, the role of the CP43/psbC protein has been described as non-essential for the PSII core assembly [2]. Other studies have found it however helps with the accumulation of the PSII complexes and light harvesting efficiency [3].

The second gene in this part, psbA, encodes the D1 subunit of PSII. Along with the psbD which encodes the D2 subunit, it forms a heterodimer. This forms the PSII reaction centre [4] which is responsible for electron transfer from chlorophyll P680 to quinones QA and QB. It is also vital to the assembly of the oxygen evolving complex and QB within PSII [5].
