Chromatophore (bacteria)
What are chromatophores?[edit | edit source]
In some forms of photosynthetic bacteria, a chromatophore is a coloured, membrane-associated vesicle used to perform photosynthesis.
What do the chromatophores contain?[edit | edit source]
- The chromatophores contain different coloured pigments. Chromatophores contain bacteriochlorophyll pigments and carotenoids.
- In purple bacteria, such as Rhodospirillum rubrum, the light-harvesting proteins are intrinsic to the chromatophore membranes.
- However, in green sulfur bacteria, they are arranged in specialized antenna complexes called chlorosomes
