It also has teichoic acids, galactans, and phenolic glycolipids in the cell wall. In addition, it is a porin similar to OmpA. This microorganism is most likely related to

Bacterial Hopanoids – The Lipids That Last Forever
WebIn our previous studies, a new opioid (NFEPP) was developed to only selectively bind to the μ-opoid receptor (MOR) in inflamed tissue and thus avoid the severe side effects of fentanyl. We know that NFEPP has a reduced binding affinity to MOR in healthy tissue. Inspired by the modelling and simulations performed by Sutcliffe et al., we present our … Hopanoids are a diverse subclass of triterpenoids with the same hydrocarbon skeleton as the compound hopane. This group of pentacyclic molecules therefore refers to simple hopenes, hopanols and hopanes, but also to extensively functionalized derivatives such as bacteriohopanepolyols (BHPs) … See more About 10% of sequenced bacterial genomes have a putative shc gene encoding a squalene-hopene cyclase and can presumably make hopanoids, which have been shown to play diverse roles in the See more Hopanoids have been estimated to be the most abundant natural products on Earth, remaining in the organic fraction of all sediments, … See more Squalene synthesis Since hopanoids are a C30 terpenoid, biosynthesis begins with isopentenyl pyrophosphate (IPP) and dimethylallyl pyrophosphate (DMAP), which are combined to form longer chain isoprenoids. Synthesis of these … See more Industry The elegant mechanism behind the protonase activity of squalene-hopene cyclase was appreciated and adapted by chemical engineers at the University of Stuttgart, Germany.
