Siderophore

The structures of 5-ethyl-1 ]-methyl-9-oxo-5,l l-dihydro-9/7-pyrido[2,1-6]-quinazohne-8-carboxylic acid (00K669), the chromophore 4 of isopyoverdin siderophores (01T1019), and that of 5,5n,6,7,8,9-hexahydro-l l//-pyrido [2,]-6]quinazoline (99SL1383) were justified by X-ray analysis. [Pg.260]

Siderophores like desferrioxamine may, therefore, find increasing applications not only in the treatment of iron poisoning and iron-overloaded disease states but also as chemotherapeutic agents, although the possible problems noted above cannot be ignored. [Pg.474]

In response to iron deprivation, E. chrysanthemi induces the synthesis of siderophores and also the transcription of pectate lyase genes (52). The pelB, pelC, pelE and pelL genes are induced under Umited iron-deprivation whereas pelD is only induced under severe iron-deprivation (53). Iron sensing in E. [Pg.321]

Soft rot spreading depends on the efficiency of the iron uptake pathway mediated by the siderophore chrysobactin. Biosynthesis of the ferrichrysobactin outer membrane receptor (Fct) and of the chrysobactin precursor, i.e. the activated form of 2,3-dihydroxybenzoic acid, are encoded by an operon,/cr ebsCEBA [3]. [Pg.875]

Iff the light of the above data, we examined the incidence of the cbrA21 (chrysobactin siderophore produced constitutively) and kdgR mutations on the transcriptional activity of pel genes. We chose to study pelD uidA and pelE uidA that proved to be well expressed in planta and whose suceptibility to iron limitation is different ... [Pg.877]

The mutant L37 cbrA21 is affected as regards to its iron uptake pathway mediated by the siderophore achromobactin. Because this mutation results in derepression of the chrysobactin mediated iron transport pathway, the mutant is probably less susceptible to iron deprivation than wild-type cells are, when entering the host. This results in a delay in Pels production thus leading to delayed symptoms, as reported by Sauvage and Expert (1994). [Pg.879]

Although Fe is required as a trace element, its uptake is critically regulated since excess leads to the generation of toxic hydroxyl radicals, and complex interactions involving Fe(II) and Fe(HI) exist within the cell (Touati et al. 1995). The role of Fe(III)-complexing siderophores in maintaining homeostasis has been noted in Chapter 3, Part 5. Details of the role of Fe and its relation to the... [Pg.254]
