Metabolite Identification

Common Name

Fumisoquin B

Description

Fumisoquin B is a secondary metabolite belonging to the chemical class of isoquinolines. Its biosynthesis is primarily facilitated by the fsqB gene in the filamentous fungus Aspergillus fumigatus, which encodes a flavoprotein from the amine oxidase family. This enzyme, part of the sarcosine oxidase family, exhibits notable activity in oxidizing L-N-methyl-amino acids, including both enantiomers of N-methyl-dopa (PMID:37968575 ). The gene cluster responsible for fumisoquin biosynthesis highlights the intricate pathways involved in the production of this compound, linking it to broader metabolic processes within the organism. Fumisoquin B's structure and synthesis pathways suggest potential roles in fungal metabolism and interactions, although its specific biological functions remain to be fully elucidated (PMID:30194285 ).
