Initiation of sporulation in B. subtilis is controlled by a multicomponent phosphorelay.
Stage 0 sporulation (spo0) mutants of Bacillus subtilis are defective in the signal transduction system initiating sporulation. Two of the products of these genes, Spo0A and Spo0F, are related to response regulator components of two-component regulatory systems used to control environmental responses in bacteria. The Spo0F response regulator was found to be the primary substrate for phosphoryla...
متن کاملKeeping signals straight in phosphorelay signal transduction.
Bacteria are highly adaptable organisms capable of growth on countless carbon and nitrogen sources and of occupying an inexhaustible variety of ecological niches. Any particular bacterium possesses a subset of these capabilities that are encoded by a repertoire of genes normally kept unexpressed unless called upon. The key to adaptability in bacteria is their capacity to express only those gene...
متن کاملHpr (ScoC) and the phosphorelay couple cell cycle and sporulation in Bacillus subtilis.
Bacillus subtilis sporulation is a developmental process that culminates in the formation of a highly resistant and persistent endospore. Inhibiting DNA synthesis prior to the completion of the final round of DNA replication blocks sporulation at an early stage. Conditions that prevent compartmentalization of gene expression, i.e. inhibition of asymmetric septum formation or chromosome partitio...
متن کاملPhosphorelay and transcription control in cytokinin signal transduction.
The past decade has seen substantial advances in knowledge of molecular mechanisms and actions of plant hormones, but only in the past few years has research on cytokinins begun to hit its stride. Cytokinins are master regulators of a large number of processes in plant development, which is known to be unusually plastic and adaptive, as well as resilient and perpetual. These characteristics all...
متن کاملSignal decay through a reverse phosphorelay in the Arc two-component signal transduction system.
Escherichia coli senses and signals anoxic or low redox conditions in its growth environment by the Arc two-component system. Under those conditions, the tripartite sensor kinase ArcB undergoes autophosphorylation at the expense of ATP and subsequently transphosphorylates its cognate response regulator ArcA through a His --> Asp --> His --> Asp phosphorelay pathway. In this study we used variou...
