Biosynthesis and Heterologous Production of Mycosporine-Like Amino Acid Palythines

The Journal of Organic Chemistry, 2021
Mycosporine-like amino acids (MAAs) are a family of natural products that are produced by a variety of organisms for protection from ultraviolet damage. In this work, we combined different bioinformatic approaches to assess the distribution of the MAA biosynthesis and identified a putative gene cluster from Nostoc linckia NIES-25 that encodes a short ...

Photophysicochemical characterization of mycosporine-like amino acids in micellar solutions

Photochemical & Photobiological Sciences, 2017
The properties and photochemical and photophysical behavior of the mycosporine-like amino acids (MAAs) shinorine and porphyra-334 were experimentally evaluated in solutions of direct ionic micelles as simple biomimicking environments. The preferential partition of the natural molecules in the aqueous phase of sodium dodecyl sulfate (SDS) or ...

Argentine squid (Illex argentinus): A source of mycosporine-like amino acids with antioxidant properties.

Food Chemistry, 2023
Here we report on the occurrence of mycosporine-like amino acids (MAAs) in the Argentine shortfin squid, Illex argentinus, the second fishery resource mostly exploited in the Argentinean continental shelf.

Inhibition of Collagenase by Mycosporine-like Amino Acids from Marine Sources [PDF]

Planta Medica, 2015
Matrix metalloproteinases play an important role in extracellular matrix remodeling. Excessive activity of these enzymes can be induced by UV light and leads to skin damage, a process known as photoaging. In this study, we investigated the collagenase inhibition potential of mycosporine-like amino acids, compounds that have been isolated from marine ...

Extraction and Analysis of Mycosporine-Like Amino Acids in Marine Algae

2015
Marine organisms use mycosporine-like amino acids (MAAs) as biological sunscreens for the protection from damaging ultraviolet (UV) radiation and the prevention of oxidative stress. MAAs have been discovered in many different marine and freshwater species including cyanobacteria, fungi, and algae, but also in animals like cnidarian and fishes. Here, we

Mycosporine‐Like Amino Acids in Harmful Marine Microalgae

Journal of Phycology, 2002
AbstractTwo current environmental issues are the increasing occurrence of harmful algal blooms and the increasing level of ultraviolet radiation. The objective of this ongoing project is to investigate whether there is a coupling between these two phenomena, i.e.

Wavelength dependence of mycosporine-like amino acid synthesis in Gyrodinium dorsum

Journal of Photochemistry and Photobiology B: Biology, 2002
The synthesis or accumulation of mycosporine-like amino acids (MAAs) is an important UV tolerance mechanism in aquatic organisms. To investigate the wavelength dependence of MAA synthesis in the marine dinoflagellate Gyrodinium dorsum, the organism was exposed to polychromatic radiation (PAR and UV) from a solar simulator for up to 72 h.
