The light absorption processes associated with photosynthesis take place in large protein complexes known as photosystems. The one known as Photosystem II contains the same kind of chlorophyll a as Photosystem I but in a different protein environment with an absorption peak at 680 nm. Complex metabolic processes such as photosynthesis and respiration coexist and predominantly occur in highly specialised thylakoid membranes. The photosynthetic and respiratory electron transport chain shares several components between these processes, a situation unique to oxygenic photosynthetic organisms.

An international team of researchers has solved the structure and elucidated the function of photosynthetic complex I. This membrane protein complex plays a major role in dynamically rewiring photosynthesis. As the first phase of photosynthesis is light dependent, it is referred to as light reaction; however this is also called. Hill’s reaction for, it was first demonstrated by Robert Hill. Basic principles involved in photosynthesis is capturing of solar electromagnetic radiations at a particular wave length by pigment/protein complexes. Graham Fleming, a physical chemist who holds joint appointments with the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) at Berkeley, is the leader of an ongoing effort to discover how plants are able to transfer energy through a network of pigment-protein complexes with nearly 100-percent efficiency. Photosynthetic complex I is a key element in photosynthetic electron transport, but little has been known about it so far.

There are two main constituent proteins in the core complex: light-harvesting complex I (LH1) and the reaction center (RC). Photosynthesis - Photosynthesis - Proteins: Many of the lamellar proteins are components of the chlorophyll–protein complexes described above. Other proteins include enzymes and protein-containing coenzymes.

"This book was very enjoyable and informative to read and should prove to be an invaluable resource for graduate students and other scientists with interests in structure and function of membrane protein complexes, in general, and photosynthetic electron-transport phenomena, in particular." Our MS analysis successfully identified major protein complexes and regulatory proteins of plant photosynthesis electron transport. The major complexes identified include PS II, PS I, cyt b6f, ATPase, and NDH, as well as the apoproteins of LHC I and LHC II. In photosynthetic bacteria, these two steps are carried out in the large membrane protein assembly called the photosynthetic core complex. There are two main constituent proteins in the core complex: light-harvesting complex I (LH1) and the reaction center (RC).

In Vitro Reconstitution of Light-harvesting Complexes of Plants

31 May 2017 Abstract.

Multiscale computational studies of biological light capture

The light absorption processes associated with photosynthesistake place in large protein complexes known as photosystems. The one known as Photosystem I contains a chlorophylldimer with an absorption peak at 700 nm known as P700. Photosystems are functional and structural units of protein complexes involved in photosynthesis that together carry out the primary photochemistry of photosynthesis: the absorption of light and the transfer of energy and electrons.
