Microviridin

Microviridin is a class of peptides that are produced by certain cyanobacteria. These peptides are known for their unique structure and bioactivity, particularly their ability to inhibit serine proteases.

Structure

Microviridins are characterized by their unusual structure, which includes a macrocyclic tris-thioether core and two lactone rings. This structure is believed to contribute to their bioactivity. The peptides are synthesized by a unique nonribosomal peptide synthetase-polyketide synthase hybrid pathway.

Bioactivity

Microviridins are known for their ability to inhibit serine proteases, a group of enzymes that play key roles in various biological processes. This bioactivity has led to interest in microviridins for potential therapeutic applications. However, further research is needed to fully understand their mechanism of action and potential uses.

Production

Microviridins are produced by certain cyanobacteria, a group of bacteria that obtain their energy through photosynthesis. The genes responsible for microviridin production have been identified in several cyanobacterial species, including Microcystis aeruginosa and Planktothrix agardhii.
