High impact information on psbB

  • In atmak3-1, the synthesis of the plastome-encoded photosystem II core proteins D1 and CP47 is affected, resulting in a decrease in the abundance of thylakoid multiprotein complexes [1].
  • In vivo protein labeling, in vitro phosphorylation, and immunoblot experiments revealed that the psbB gene product (CP47) and an 8-kD phosphoprotein, the psbH gene product (PsbH), are absent in mutant plants [2].
  • Immunological analysis of the photosystem II protein complement indicated that significant losses of the CP47, CP43, and D1 proteins occurred upon the loss of the manganese-stabilizing proteins [3].
  • Here we describe the identification of the HCF107 gene that is involved in the 5'-end processing/stability and/or translation of the psbH gene and in the translation of the psbB gene [4].
  • Expression of the genes of plastidial psbB operon (psbB-psbT-psbH-petB-petD) involves multiple processing events and formation of several mono-, di- and multi-cistronic transcripts which are further regulated by differential stability and expression [4].
 

Other interactions of psbB

  • Thus, by specific transcription initiation at the psbN gene promoter, SIG3-PEP holoenzyme could also influence the expression of the psbB operon by producing psbT antisense RNA [5].
 

Analytical, diagnostic and therapeutic context of psbB

  • (3) The ratio of the light-harvesting complex II apoproteins (LHCP) to 47-kDa chlorophyll a protein (CP47), which was estimated by the results of immunoblotting, increased by 40% [6].
