Article Synopsis
  • A new light-harvesting complex called LL LH2 was discovered alongside the known LH4 complex in cells exposed to low light conditions.
  • Advanced techniques like FPLC-MS/MS identified specific proteins and carotenoids unique to LL LH2, distinguishing it from LH4.
  • Structural analysis revealed different amino acid sequences and interactions between proteins and pigments, suggesting that LL LH2 operates with lower energy transfer efficiency compared to LH4, establishing it as a distinct type of light-harvesting complex.

Preservation of health, increase in life expectancy determine the need to improve the effectiveness of medical recommendations, which, despite the success of pharmacology, are insufficient for reasons related to the low level of compliance with these recommendations by patients. The authors of the article believe that compliance is a kind of quantifiable and behaviorally realized reflection of therapeutic interaction, refracted through the prism of the patient's individual personality characteristics. Participants of the study-148 employees of medical institutions: 12 men, 136 women, their age ranged from 27 to 74 years.

The predominance of the maximum at 800 nm for the light-harvesting complex LH4 (B800) and at 850 nm for LH2 (B800-850) from Rps. palustris is determined by the composition of αβ-polypeptides and pigments. In low light (LL) for Rps.

A pigment-protein complex of yellow color with absorption maxima at 682 and 776 nm, characteristic for bacteriophytochromes, was isolated from the photosynthetic membranes of the purple bacterium Rhodopseudomonas palustris. Zinc-induced fluorescence of the complex indicated the presence of the biliverdin chromophore covalently bound to the protein. The parameters of low-temperature fluorescence (λ excitation at 680 nm, λ emission at 695 nm) indicated the ability of the complex to undergo photoconversion.
