Allgemeine Beschreibung
3,3′-Dithiodipropionic acid forms monolayers on a polycrystalline gold electrode through a self-assembly procedure to form gold 3,3′-dithiodipropionic acid self-assembled monolayer modified electrode. It is the precursor substrate in the synthesis of 3-mercaptopropionic acid-containing polythioesters. It is added as primary carbon supplement in the culture medium of novel betaproteobacterium, strain DPN7.
Research
Besides 3MP, also the organic sulfur compounds (OSCs) 3,3'-thiodipropionic acid (TDP) and 3,3'-dithiodipropionic acid (DTDP) are established precursor substrates for poly(3HB-co-3MP) biosynthesis in R. eutropha H16. Both precursors offer advantages in comparison to 3MP. While higher concentrations of 3MP seriously impair growth of R. eutropha H16, TDP and DTDP are nontoxic OSCs[1-2].
