Structural mechanism and photoprotective function of water-soluble chlorophyll-binding protein.
A water-soluble chlorophyll-binding protein (WSCP) is the single known instance of a putative chlorophyll (Chl) carrier in green plants. Recently the photoprotective function of WSCP has been demonstrated by EPR measurements; the light-induced singlet-oxygen formation of Chl in the WSCP tetramer is about four times lower than that of unbound Chl. This paper describes the crystal structure of th...
متن کاملSynthesis and DNA-binding properties of water-soluble cationic pyropheophorbides derived from chlorophyll a/b.
A series of mono-, di-, tetra- and hexacationic esters of pyropheophorbide a/b have been designed and synthesized to explore the intercalation of their phorbine ring between the base pairs of double-helical DNA and the influence of their peripheral substituents on the DNA interactions. Mono-(1), di-(2, 3) and tetra-(4, 5) cationic pyropheophorbides are soluble as an oligomeric aggregate in HEPE...
متن کاملA novel role of water-soluble chlorophyll proteins in the transitory storage of chorophyllide.
All chlorophyll (Chl)-binding proteins involved in photosynthesis of higher plants are hydrophobic membrane proteins integrated into the thylakoids. However, a different category of Chl-binding proteins, the so-called water-soluble Chl proteins (WSCPs), was found in members of the Brassicaceae, Polygonaceae, Chenopodiaceae, and Amaranthaceae families. WSCPs from different plant species bind Chl...
متن کاملIntegration of a chlorophyll-binding protein into Escherichia coli membranes in the absence of chlorophyll.
The mechanism by which a protein integrates posttranslationally into a membrane can involve the composition of the membrane itself, domains within the inserting polypeptide, and a number of associating proteins. Some integral membrane proteins do not accumulate to normal levels when certain pigments are deficient, and this has been interpreted to mean that such proteins may be rapidly degraded ...
متن کاملMolecular Cloning and Functional Expression of A Class IIA Water-Soluble Chlorophyll-Binding Protein From Brassica nigra
Non-photoconvertible water-soluble chlorophyll-binding proteins, called Class II WSCPs, have been identified in some Brassicaceae plants. Although the WSCP in black mustard (Brassica nigra) was the second Class II WSCP to be reported by Murata and Murata, the cDNA has not been cloned until now. In this study, we cloned a cDNA encoding the black mustard WSCP (BmWSCP) and analyzed its chlorophyll...
