Phycobilisomes and their constituents

The unique structure of the phycobilisome determines its function in photosynthesis. The energy of light absorbed by phycobilisomes decreases gradually from the

On the other, PBSs linkers function to stabilize PBSs structure and determine positions of the PBPs within PBSs structure. At the same time, PBSs linkers also interact directly or indirectly The cyanobacterial photosynthetic apparatus is remarkably similar in structure and function to that found in the chloroplasts of eucaryotic algae and higher plants (Bryant, 1987). Four major Considering the highly conserved function of PBS to transfer energy to both PSI and PSII, it is not surprising that the basic structure of the PBS core remains unchanged in

The structure and function of linker peptides in PBSs have shown a great diversity based on the light condition [1, 22]. The method to respond to high-light stress in marine

The structures and functions of the PBPs have been extensively studied for decades, and a series of reviews concerning these findings have been published [1,2,4,5,9– 14].

Future studies on structure and function of linker polypeptides will require more effective approach that will allow their study in solution in the absence of PBP.

Cyanobacterial Phycobilins: Production, Purification, and Regulation

How can Phycobilisome, the unique light harvesting system in certain algae working highly efficiently: The connection in between structures and functions Summary Phycobilisomes are aggregates of light-harvesting proteins attached to the stroma side of the thylakoid membranes of the cyanobacteria (blue-green algae) and red algae. The water Journal of bacteriology, 1987 Several cyanobacteria adjust both the phycobiliprotein and linker protein composition of the phycobilisome, a light-harvesting complex in cyanobacteria and

The phycobilisome (PBS) is the major light-harvesting apparatus in cyanobacteria and red algae. It is a large multi-subunit protein complex of several megadaltons that is found The phycobilisome (PBS) antenna present in cyanobacteria was replaced by Chl a/b- or Chl a/c-containing pigment–protein complexes in most groups of photosynthetics. In the Several recent reviews haveextensively covered various aspects of PBsome structure and function andshould beconsulted for detailed n- formation on earlier work[21, 35-37, 5054, 100,

How can Phycobilisome, the unique light harvesting system in certain algae working highly efficiently: The connection in between structures and functions Since the phycobilisome is an abundant component of the cell, its degradation may provide a substantial amount of nitrogen to nitrogen-limited cells. Furthermore, degradation of the

The degree of preservation of phycobilisome structure and function can be assessed by three complementary types of analyses. Transmission electron microscopy of Phycobilisomes are megacomplexes in cyanobacteria that capture light. Here, authors characterize a relict paddle-shaped phycobilisome structure, revealing phycobilisome Phycobilisomes, which biochemically consist of phycobiliproteins and linker polypeptides, are particularly wonderful subjects for the detailed analysis of structure and

The unique structure of the phycobilisome determines its function in photosynthesis. The energy of light absorbed by phycobilisomes decreases gradually from the periphery to the core. Several recent reviews haveextensively covered various aspects of PBsome structure and function andshould beconsulted for detailed n- formation on earlier work[21, 35-37, 5054, 100, Phycobilisomes (PBSs) are light-harvesting antenna complexes in cyanobacteria that adapt to diverse light environments through the use of phycobiliproteins within the PBS

Light energy is absorbed and then transferred through the rods and cores to photosystems I and II. Now, by using cryo-electron microscopy, Koji Yonekura, also at the X-ray crystallographic structure of the light-harvesting biliprotein C-phycocyanin from the thermophilic cyanobacterium Mastigocladus laminosus and its resemblance to globin structures

The L cm polypeptide has several functions, including the linker function of determining the organization of the phycobilisome cores. Details of how linkers perform their This review focuses on the current status of PBPs, their structure, functions, methods of preparation, and applications. Additionally, the stability, bioavailability, and safety The phycobilisome (PBS) is an antenna protein complex in cyanobacteria, Glaucocystophytes, and red algae. In the standard PBS, the rod-core PBS, the rods are
