Indole sesquiterpene sespendole, which has been isolated from the filamentous fungus Pseudobotrytis terrestris FKA-25, is a specific inhibitor of lipid droplet synthesis in mouse macro-phages. The biosynthetic pathway that involves genes encoding six enzymes (spdEMBQHJ) was elucidated through heterologous expression of spd genes in Aspergillus oryzae, biotransfor-mation experiments, and in vitro enzymatic reactions with a re-combinant protein, thereby revealing the mechanism underlying the characteristic modification on the indole ring, catalyzed by a set of prenyltransferase (SpdE)/cytochrome P450 (SpdJ) enzymes. Functional analysis of the homologous genes encoding these enzymes involved in the biosynthesis of lolitrem allowed a biosynthetic pathway for the bicyclic ring skeleton fused to the indole ring to be proposed.
