The 9-kDa Phosphoprotein Involved in Photoinhibition
Photosystem-II particles exhibit strong photoinhibition. Short-term illumination of photosystem-II particles with high-intensity light (5000 piE/m x s) leads to a typical change of the protein pattern on SDS-PAGE. Two proteins are mainly affected, namely the well-described 32-kDa herbicide-binding protein which probably is degraded [1] and, first published here, the 9-kDa phosphoprotein, whose ...
متن کاملAmino acid sequence of the 9-kDa iron-sulfur protein of photosystem I in barley.
The 9-kDa thylakoid polypeptide which in vivo carries the iron-sulfur centers A and B of photosystem I was isolated from barley (Hordeum vulgare L.) and the complete amino acid sequence determined. The polypeptide shows a very high degree of homology with the corresponding polypeptides in other plant species. The polypeptide is not post-translationally processed except for the removal of the N-...
متن کاملTopological studies of spinach 22 kDa protein of Photosystem II.
An intrinsic 22 kDa polypeptide is associated with the O2-evolving Photosystem II core complex in a variety of green plants, although it does not appear to be required for O2 evolution. Digestion of thylakoid membranes and isolated Photosystem II preparations with trypsin, followed by immunoblotting using spinach anti-22 kDa antibodies, leads to two observations: (1) the domain between the 2nd ...
متن کاملMMP 9 ( matrix metallopeptidase 9 ( gelatinase B , 92 kDa gelatinase , 92 kDa type IV collagenase ) )
MMP-9 is a Zn+2 dependent endopeptidase, synthesized and secreted in monomeric form as zymogen. The structure is almost similar to MMP2, another member of matrixmetalloproteinase family. The nascent form of the protein shows an N-terminal signal sequence ('pre' domain) that directs the protein to the endoplasmic reticulum. The pre domain is followed by a propeptide-'pro' domain that maintains e...
متن کاملA Nucleus-Encoded Chloroplast Phosphoprotein Governs Expression of the Photosystem I Subunit PsaC in Chlamydomonas reinhardtii.
The nucleo-cytoplasmic compartment exerts anterograde control on chloroplast gene expression through numerous proteins that intervene at posttranscriptional steps. Here, we show that the maturation of psaC mutant (mac1) of Chlamydomonas reinhardtii is defective in photosystem I and fails to accumulate psaC mRNA. The MAC1 locus encodes a member of the Half-A-Tetratricopeptide (HAT) family of sup...
