fbfB, a gene encoding a putative galactose oxidase, is involved in Stigmatella aurantiaca fruiting body formation.
Stigmatella aurantiaca is a gram-negative bacterium which forms, under conditions of starvation in a multicellular process, characteristic three-dimensional structures: the fruiting bodies. For studying this complex process, mutants impaired in fruiting body formation have been induced by transposon insertion with a Tn5-derived transposon. The gene affected (fbfB) in one of the mutants (AP182) ...
متن کاملPhotocontrol of development by Stigmatella aurantiaca.
Aggregation and fruiting body formation by Stigmatella aurantiaca were stimulated most effectively by low irradiances of blue light between 400 and 500 nm. At higher irradiances, other wavelengths of light, including those in the far-red region of the spectrum, were also effective.
متن کاملLocalization of the stress protein SP21 in indole-induced spores, fruiting bodies, and heat-shocked cells of Stigmatella aurantiaca.
The localization and distribution of the stress protein SP21 in indole-induced vegetative cells, fruiting bodies, and heat shocked cells of Stigmatella aurantiaca were determined by immunoelectron microscopy. SP21 was found at the cell periphery in heat-shocked cells and either at the cell periphery or within the cytoplasm in indole-induced cells, often concentrated in clusters. In fruiting-bod...

The field of bacterial natural product research is currently undergoing a paradigm change concerning the discovery of natural products. Previously most efforts were based on isolation of the most abundant compound in an extract, or on tracking bioactivity. However, traditional activity-guided approaches are limited by the available test panels and frequently lead to the rediscovery of already k...
متن کاملStimulation of inositide degradation in clumping Stigmatella aurantiaca.
Numerous external signals which activate inositol phospholipid hydrolysis in eukaryotes are known; probably all of these signals are transduced by G proteins. So far, neither signal-transducing G protein nor receptor-regulated phospholipase C has been found in prokaryotes. However, a group of bacteria, the myxobacteria, displays cellular and tissue-like differentiation; therefore, it appeared t...
