We will focus on altering the quantity of the Light Harvesting Complex 2 (LH2) by regulating the pucB/A genes that code for the two subunits of the complex. LH2 absorbs photons maximally at the wavelength of 842 nm and funnels its energy to LH1 and the reaction center. The ratio of LH2 complexes to LH1 naturally ranges from 3.0 to 6.7 under varying light conditions (Scheuring et al., 2005). We propose that if this ratio of LH2 to LH1 is altered to range from 0-7 or more in response to incidental light intensity, then the photosynthetic efficiency and productivity for a culture of R. sphaeroides may be maximized. | We will focus on altering the quantity of the Light Harvesting Complex 2 (LH2) by regulating the pucB/A genes that code for the two subunits of the complex.
