Prodigiosin functions

Artificial analogues of the chloride transporter prodigiosin are effective symport HC1 carriers as exemplified in the model systems developed by the groups of Gale [39] and Davis [40], Biological inspiration is also behind another Cl- carrier. Cholic acid is a naturally occurring bile acid that functions as a surfactant in the intestine. Derivatives with three binding sites known as cholapods are able to transport isolated anions across lipid bilayers [41],...

Prodigiosin may function in air dispersal of Serratia marcescens [250]. The pigmented strain is much more able than the non-pigmented strain to adsorb onto air bubbles and enrich the drops formed on breakage of the bubbles. Also prodigiosin makes hydrophobic the normally hydrophilic cells. The pigment itself is hydrophobic.
