摘要
To investigate the feasibility of using near-infrared absorption to predict stability of light-harvesting complex 2 from the purple bacteria, we compared the structural stability of light-harvesting complex 2 with different absorption properties. The spectral changes showed that light-harvesting complex 2 from Rhodobacter azotoformans (absorption maxima at 799 and 847nm) was more susceptible to both sodium-dodecylsulfate and acid than light-harvesting complex 2 from Rhodopseudomonas palustris (absorption maxima at 803 and 857nm). It is concluded that a relatively redshifted near-infrared absorption tends to indicate a more stable structure of light-harvesting complex 2.
