The relationship between carotenoid biosynthesis and the assembly of the light-harvesting LH2 complex in Rhodobacter sphaeroides.

The Biochemical journal - 15 Feb 1994

Lang H P, Hunter C N

Abstract excerpt

Coloured carotenoids play some undefined role in the assembly of a functional light-harvesting 2 (LH2) complex in photosynthetic bacteria. We have used a series of transposon Tn5 insertion mutants disrupted at various stages of the carotenoid-biosynthetic pathway, together with an LH2 deletion/insertion mutant, to investigate this effect in Rhodobacter sphaeroides. Mutants were initially characterized by...
