![]() A reduced efficiency for the oxidation of side-pathway donors in the D1:1 variant could be explained by a variation in the location and/or redox potential of P +. We suggest that this state is blue-shifted in the D1:1 variant. This establishment can be found at the following address: United States, Rockville Centre, NY 11570, 5 Olive Ct. Photo-induced Q A − formation with far red light is assigned to the direct optical excitation of a weakly absorbing charge transfer state of the reaction centre. The reduced yield with red light in the D1:1 variant could be associated with either the Glu130Gln change, and/or the four changes near the binding site of P D1, in particular Ser153Ala. The effects on the pheophytin Q x band can be attributed to the hydrogen bond from Glu130 in D1:3 to the 13 1-keto of Pheo D1, which is absent for Gln130 in D1:1. These effects can be correlated with amino acid changes between the two D1 variants. Illuminations offers a 5,000 square foot showroom with a range of lighting fixtures and accessories. (iv) For the D1:1 variant, the quantum efficiency of photo-induced oxidation of side-pathway donors was lower. We have compared steady state absorption and photo-induced difference spectra at 50 ms) Q A − yield was ∼ 95% in D1:3, and ∼ 60% in D1:1, relative to green light excitation. These genes encode for the D1 protein variants labeled D1:3 and D1:1, respectively. In Photosystem II (PSII) from Thermosynechococcus elongatus, high-light intensity growth conditions induce the preferential expression of the psbA 3 gene over the psbA 1 gene. the Glenview Mansion Art Gallery in Rockville, Maryland the Fraser Gallery in Bethesda, Maryland the Ellipse Arts Center in Arlington, Virginia.
