The heliobacteria, a family of anoxygenic phototrophs, are significant to photosynthesis evolution research, as they possess the simplest known photosynthetic apparatus. Although they are photoheterotrophs in the light, the heliobacteria may also grow chemotrophically via pyruvate metabolism in the absence of light. In Heliobacterium modesticaldum, the cytochrome bc complex is responsible for oxidizing menaquinol and reducing cytochrome c553 in the electron flow cycle used for phototrophy.
