LH2: A peripheral light-harvesting complex in purple bacteria, typically composed of BChl and Car, which funnels excitation energy to the reaction centre.

Researchers at the University of Tsukuba have reported on the structure and light energy transfer efficiency of a protein complex crucial to the photosynthesis of purple sulfur bacteria thriving ...

Light-harvesting protein complexes -- specifically the light-harvesting two complex (LH2) ... 2024 — Purple sulfur bacteria (PSB) convert light energy into chemical energy through photosynthesis.

For this study, the MIT team focused on purple bacteria, which are often found in oxygen-poor aquatic environments and are commonly used as a model for studies of photosynthetic light-harvesting.

When photosynthetic cells absorb light from the sun, packets of energy called photons leap between a series of light-harvesting proteins until they reach the photosynthetic reaction center. There, ...

According to the study, purple bacteria adapt to different light intensities by changing the arrangement of the light harvesting mechanism, but not in the way one would think by intuition.

A purple bacteria which stores energy from light can help harvest hydrogen fuel from sewage, and recover carbon from any type of organic waste, scientists have found. Organic compounds in ...

Light-harvesting protein complexes—specifically the light-harvesting two complex (LH2) and the core light-harvesting reaction center complex (LH1-RC)—play a crucial role in this process.

For this study, the researchers embedded two versions of the primary light-harvesting protein found in purple bacteria, known as LH2 and LH3, into their nanodiscs.
