Effect of carotenoids and monogalactosyl diglyceride on bacteriochlorophyll c aggregates in aqueous buffer: Implications for the self-assembly of chlorosomes
Original language description
Aggregation of bacteriochlorophyll (BChl) c from chlorosomes, the main light-harvesting complex of green bacteria, has been studied in aqueous buffer. Unlike other chlorophyll-like molecules, BChl c is rather soluble in aqueous buffer, forming dimers. When BChI c is mixed with carotenoids (Car), the BChl c Q(y) transition is further redshifted, in respect to that of monomers and dimers. The results suggest that Car are incorporated in the aggregates and induce further aggregation of BChl c. The redshiftof the BChl c Q(y) band is proportional to the Car concentration. In contrast, the mixture of bacteriochlorophyllide (BChlide) c, which lacks the nonpolar esterifying alcohol, does not form aggregates with Car in aqueous buffer or nonpolar solvents. Instead, the position of the BChlide c Q(y) transition remains unshifted in respect to that of the monomeric molecule, and Car precipitates with the course of time in aqueous buffer. Similar effects on both BChl c and BChlide c are also obse

Efekt karotenoidů a monogalaktosyl diglyceridu na agregáty bakteriochlorofylu c ve vodném pufru: Důsledky pro samoorganizaci chlorosomu.
Czech description
Karotenoidy jsou nutné pro vytvoření bakteriochlorofylových agregátů jejichž vlastnosti se podobají chlorosomálním anténám v zelených sirných bakterií. Tak byl jednoznačně prokázán vliv karotenoidů na samoorganizaci bakteriochlorofylových agregátů.
