Glycogen, hyaluronate, and some other polysaccharides greatly enhance the formation of exolipase by Serratia marcescens

Abstract

Among 21 different polysaccharides tested, 5 greatly enhanced the spontaneous and cyclic AMP-induced formation of exolipase: glycogen, hyaluronate, laminarin, pectin B, and gum arabic. These polysaccharides have in common the tendency to form highly ordered networks because of the branching or helical arrangement, or both, of their molecules. None of the polysaccharides could be utilized by the cells as the sole carbon source. Strong lipid extraction of four different polysaccharides did not reduce their exolipase-enhancing efficacy. At a constant cell density the stimulation of exolipase formation by various concentrations of glycogen followed saturation kinetics, suggesting a limited number of "sites" for the glycogen to act. The active principle present in a solution of pectin was destroyed by degradation (beta-elimination) of the polymer. Hyaluronate lost its exolipase-enhancing activity by exhaustive hydrolysis with hyaluronidase but was resistant to proteinase K. Exopolysaccharide, isolated from growth medium of Serratia marcescens SM-6, enhanced the exolipase formation as efficiently as hyaluronate. The results of this work are discussed mainly in terms of the "detachment hypothesis."

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
