Metabolic Modification of Escherichia coli BL21 (DE3) to Produce Shinorine

Shinorine, a naturally occurring UV-absorbing compound belonging to the class of mycosporine-like amino acids (MAAs), has attracted considerable attention for its applications in pharmaceuticals, cosmetics, and biomaterials. However, conventional production methods based on extraction from marine organisms are constrained by low yield, limited ...

Nature‐Inspired Uv Filters: Synthetic Mycosporine‐Like Amino Acids and Gadusol Analogs for Enhanced Photoprotective and Antioxidant Performance

ChemPhotoChem, Volume 9, Issue 11, November 11, 2025.
Photoprotection is a current and relevant topic; therefore, the development of new sunscreens is necessary. To this end, nature is examined for molecules such as mycosporine‐like amino acids and gadusol. Through rational design, this study has successfully synthesized new UV filters and evaluated their photoprotective and antioxidant properties ...

Seasonal Changes in Mycosporine-Like Amino Acid Production Rate with Respect to Natural Phytoplankton Species Composition

Marine Drugs, 2015
After in situ incubation at the site for a year, phytoplanktons in surface water were exposed to natural light in temperate lakes (every month); thereafter, the net production rate of photoprotective compounds (mycosporine-like amino acids, MAAs) was ...

Extreme Environmental Variability Induces Frontloading of Coral Biomineralisation Genes to Maintain Calcification Under pCO2 Variability

Molecular Ecology, Volume 34, Issue 2, January 2025.
ABSTRACT Corals residing in habitats that experience high‐frequency seawater pCO2 variability may possess an enhanced capacity to cope with ocean acidification, yet we lack a clear understanding of the molecular toolkit enabling acclimatisation to environmental extremes or how life‐long exposure to pCO2 variability influences biomineralisation.

Constructing efficient bacterial cell factories to enable one‐carbon utilization based on quantitative biology: A review

Quantitative Biology, Volume 12, Issue 1, Page 1-14, March 2024.
Abstract Developing methylotrophic cell factories that can efficiently catalyze organic one‐carbon (C1) feedstocks derived from electrocatalytic reduction of carbon dioxide into bio‐based chemicals and biofuels is of strategic significance for building a carbon‐neutral, sustainable economic and industrial system.

Ring buckling and C=N isomerization pathways for efficient photoprotection in two nature‐inspired UVA sunscreens revealed through ultrafast dynamics and high‐level calculations

Photochemistry and Photobiology, Volume 100, Issue 2, Page 298-313, March/April 2024.
The UV filters in sunscreens are our frontline defense against the harms of ultraviolet radiation. In this paper, we continue the industry's shift toward nature‐inspired, particularly microbial, UV filters by unraveling the fundamental mechanisms of photoprotection in two synthetic analogs of mycosporine‐like amino acids.
