Article Synopsis
- Phototrophic Gemmatimonadetes gained the ability to use solar energy by acquiring photosynthesis-related genes from an ancient phototrophic proteobacterium through horizontal gene transfer.
- Electron cryo-microscopy revealed a unique double-ring structure of the photosystem, consisting of a central reaction center surrounded by two distinct antenna rings for enhanced light absorption.
- The study demonstrated that Gemmatimonadetes has evolved an efficient architecture for solar energy harvesting, featuring complex energy flow from the outer antennae to the reaction center.
Bilirubin (BR) is an essential metabolite formed by the catabolism of heme. Phototherapy with blue-green light can be applied to reduce high concentrations of BR in blood and is used especially in the neonatal period. In this work, we studied the photochemistry of ()-isovinylneoxanthobilirubic acid methyl ester, a dipyrrinone subunit of BR, by steady-state absorption, femtosecond transient absorption, and stimulated Raman spectroscopies.
