Immunomodulatory Effects of the Mycosporine-Like Amino Acids Shinorine and Porphyra-334 [PDF]

open access: yesMarine Drugs, 2016
Mycosporine-like amino acids (MAAs) are secondary metabolites, produced by a large variety of microorganisms including algae, cyanobacteria, lichen and fungi. MAAs act as UV-absorbers and photo-protectants.

Nrf2 and NF-κB Signaling Pathways Contribute to Porphyra-334-Mediated Inhibition of UVA-Induced Inflammation in Skin Fibroblasts [PDF]

open access: yesMarine Drugs, 2015
In this study, we examined the protective effects of porphyra-334 against UVA-irradiated cellular damage and elucidated the underlying mechanisms. Porphyra-334 prevented UVA-induced cell death and exhibited scavenging activities against intracellular ...

Glycosylated porphyra-334 and palythine-threonine from the terrestrial cyanobacterium Nostoc commune. [PDF]

open access: yesMar Drugs, 2013
Mycosporine-like amino acids (MAAs) are water-soluble UV-absorbing pigments, and structurally different MAAs have been identified in eukaryotic algae and cyanobacteria.

Porphyra-334 isolated from the marine algae Bangia atropurpurea: conformational performance for energy conversion. [PDF]

open access: yesMar Drugs, 2014
Prophyra-334 (p-334) may play a role of energy transfer under an uncertain mechanism, and we speculate the possible model. Via 1D and 2D NMR experiments, it was simulated the correlation between dissociation and conformation of p-334.

Antioxidant and Anti-Aging Effects of Porphyra-334 Produced from <i>Saccharomyces cerevisiae</i> in Human Skin Models. [PDF]

open access: yesMar Drugs
Porphyra-334 (PPR-334) is one of the species of mycosporine-like amino acids (MAAs), known as biological UV protection ingredients. In this study, we developed a large-scale purification process to extract PPR-334 from Saccharomyces cerevisiae and ...

Environmental adaptations by the intertidal Antarctic cyanobacterium Halotia branconii CENA392 as revealed using long‐read genome sequencing

open access: yesLimnology and Oceanography Letters, 2023
Antarctica poses numerous challenges to life such as cold shock, low nutrient concentrations, and periodic desiccation over a wide range of extreme temperatures. Cyanobacteria survive this harsh environment having evolved adaptive metabolic plasticity to

Genomic and secondary metabolites of the marine cyanobacterium Capilliphycus salinus ALCB114379. [PDF]

open access: yesJ Phycol
Abstract Assembling high‐quality genomes from underexplored environments can be helpful for understanding microbial diversity and identifying novel species. The Cyanobacterium type strain Capilliphycus salinus ALCB114379 is a representative of Oscillatoriales order isolated from a supralittoral zone of the south Atlantic Ocean in Brazil, an ecotone ...

Efficient production of mycosporine-like amino acids, natural sunscreens, in Yarrowia lipolytica. [PDF]

open access: yesBiotechnol Biofuels Bioprod, 2023
Background Mycosporine-like amino acids (MAAs), including shinorine and porphyra-334, are gaining attention as safe natural sunscreens. The production of MAAs has been achieved in diverse microbial hosts, including Saccharomyces cerevisiae.

Direct Evidence of Microbial Sunscreen Production by Scum-Forming Cyanobacteria in the Baltic Sea. [PDF]

open access: yesEnviron Microbiol Rep
We found both culture‐independent and culture‐dependent evidence for the widespread production of mycosporine‐like amino acids (MAAs) in blooms of cyanobacteria from the Baltic Sea. Using a combination of bioinformatics, microbial genetics, and mass spectrometry, we demonstrated the high‐level production of these microbial sunscreens in members of the ...
