Expression
| Organism | Comment | Expression |
|---|---|---|
| Dickeya dadantii | expression of genes faeT and faeD is not significantly affected by the addition of acetosyringone, benzoic acid, cinnamic acid, p-coumaric acid, vanillic acid, arabinogalactan, arabinose, galactose, galacturonate, mannose, pectin, polygalacturonate, rhamnose, salicine, xylose, or xylan | additional information |
| Dickeya dadantii | feruoyl esterases FaeD and FaeT are induced by ferulic acid. The product of the adjacent gene faeR is involved in the positive control of faeD in response to ferulic acid. Moreover, ferulic acid acts in synergy with polygalacturonate to induce pectate lyases, the main virulence determinant of soft rot disease | up |
General Information
| General Information | Comment | Organism |
|---|---|---|
| malfunction | when gene faeT is inactivated, the size of the esterase halo clearly decreased. When gene faeD is inactivated, only very low residual feruoyl esterase activity is detected, as observed in the faeD faeT double mutant | Dickeya dadantii |
| physiological function | the two feruloyl esterases, FaeD and FaeT, cleave the ester link between ferulate and the pectic or xylan chains. FaeD is an extracellular protein secreted by the Out system, responsible for pectinase secretion. Feruloyl esterases dissociate internal cross-links in the polysaccharide network of the plant cell wall, suppress the polysaccharide esterifications, and liberate ferulic acid, which contributes to the induction of pectate lyases. Together, these effects of feruloyl esterases could facilitate soft rot disease caused by pectinolytic bacteria. FaeD appears to be responsible for most feruloyl esterase activity in Dickeya dadantii | Dickeya dadantii |
