Metabolite Identification
Common NameDiploptene
DescriptionDiploptene is a triterpenoid belonging to the chemical class of hopanoids, which are significant metabolites found in various organisms, particularly in cyanobacteria. It is characterized as C30-hop-22(29)-ene and plays a crucial role in membrane structure and function. Diploptene is synthesized through the cyclization of squalene by the enzyme squalene-hopene cyclase, marking an essential step in hopanoid biosynthesis (PMID:34585578 ). This compound is not only prevalent in certain cyanobacterial species but also produced by various nitrogen-oxidizing bacteria (NOB), which exhibit diverse hopanoid profiles, with some strains primarily generating diploptene (PMID:35060273 ). Furthermore, diploptene is involved in biochemical reactions, such as the formation of adenosylhopane via a crosslinking reaction with a 5'-deoxyadenosyl radical, facilitated by the radical S-adenosyl-L-methionine enzyme HpnH (PMID:34506710 ). The study of diploptene and its derivatives provides insights into the depositional environments of organic matter, as evidenced by its association with long-chain and short-chain n-alkanes in sediment cores (PMID:34325152 ). Overall, diploptene serves as a critical component in both microbial ecology and biochemistry.
