What is the function of phycocyanin?

What is the function of phycocyanin?

Phycocyanin is a pigment-protein complex that biologically functions cooperatively with chlorophyll in photosynthesis. Specifically, phycocyanin increases the efficiency of chlorophyll’s oxygen production under low light conditions.

What is the function of phycoerythrin?

Phycoerythrin is an accessory pigment to the main chlorophyll pigments responsible for photosynthesis. The light energy is captured by phycoerythrin and is then passed on to the reaction centre chlorophyll pair, most of the time via the phycobiliproteins phycocyanin and allophycocyanin.

What is phycoerythrin in biology?

Phycoerythrin (PE) is a red protein pigment complex produced by the light-harvesting phycobiliprotein family. It is present in red algae and cryptophytes as an accessory to the main chlorophyll pigments responsible for photosynthesis (Ficner and Huber, 1993; van der Weij-De Wit et al., 2006).

Where is phycocyanin found?

C-phycocyanin is often found in cyanobacteria which thrive around hot springs, as it can be stable up to around 70 °C, with identical spectroscopic (light absorbing) behaviours at 20 and 70 °C. Thermophiles contain slightly different amino acid sequences making it stable under these higher conditions.

What causes phycocyanin?

The higher heating processes cause an increase in phycocyanin degradation. The interaction between microencapsulation and the temperature of heating treatment produced the highest value of phycocyanin degradation (57.23±0.16%) and antioxidant degradation (46.85±0.04%), namely S.

What is the Colour of phycocyanin?

blue colorant
Phycocyanin, a natural blue colorant, is typically extracted from liquid biomass of Arthrospira platensis, a blue-green algae called spirulina.

What is phycocyanin phycoerythrin?

Phycocyanin and phycoerythrin are photosynthetic pigments extracted from microalgae with great biotechnological potential due to their intense colors, fluorescent properties and potential health benefits.

What is the name given to the chromophore in phycocyanin?

Phycocyanobilin is a blue phycobilin, i.e., a tetrapyrrole chromophore found in cyanobacteria and in the chloroplasts of red algae, glaucophytes, and some cryptomonads. Phycocyanobilin is present only in the phycobiliproteins allophycocyanin and phycocyanin, of which it is the terminal acceptor of energy.

What is the difference between phycocyanin and phycoerythrin?

is that phycoerythrin is (protein) a red, light-harvesting protein found in cyanobacteria, red algae and cryptomonads while phycocyanin is (biochemistry) a pigment from the light-harvesting phycobiliprotein family, along with allophycocyanin and phycoerythrin, an accessory pigment to chlorophyll.

Does red algae have Phycocyanin?

The red algae were the first lineage of organisms to have true chloroplasts, derived from the endosymbiosis of a cyanobacterium, and so they have the same pigments: chlorophyll a and phycobilins. In particular, the red algae derive most of their coloring from a red phycobilin called phycoerythrin.

What is the meaning of phycocyanin?

Definition of phycocyanin. : any of various bluish-green protein pigments found in cyanobacteria.

What is the difference between allophycocyanin and phycobiliprotein?

Allophycocyanin absorbs and emits at longer wavelengths than phycocyanin C or phycocyanin R. Phycocyanins are found in Cyanobacteria. Phycobiliproteins have fluorescent properties that are used in immunoassay kits.

What is the function of phycocyanobilin?

Phycocyanobilin Phycocyanin is a pigment -protein complex from the light-harvesting phycobiliprotein family, along with allophycocyanin and phycoerythrin. It is an accessory pigment to chlorophyll. All phycobiliproteins are water-soluble, so they cannot exist within the membrane like carotenoids can.

Is phycocyanin an oxidant or an anti-oxidant?

Phycocyanin has both anti-oxidant and anti-inflammation properties. Peroxyl, hydroxyl, and alkoxyl radicals are all oxidants scavenged by C-PC. C-PC, however, has a greater effect on peroxyl radicals.
