WebDec 30, 2013 · Extracytoplasmic function (ECF) sigma factors are members of cell-surface signaling systems, abundant in the opportunistic pathogen Pseudomonas aeruginosa. Twenty genes coding for ECF sigma factors are present in P. aeruginosa sequenced genomes, most of them being part of TonB systems related to iron uptake. In this work, … WebFeb 24, 2024 · Furthermore, the search in the InterPro database indicated that LIC_10559 is an RNA polymerase σ factor that belongs to the σ 70-family (its ECF subfamily; Sigma70_ECF—IPR039425) and contains only σ2 (aa: 33–82; similarity to InterPro: IPR007627) and σ4 (aa: 119–168; similarity to InterPro: IPR013249) domains, which are …

WebSep 1, 2024 · The application of the valuable natural product thaxtomin A, a potent bioherbicide from the potato scab pathogenic Streptomyces strains, has been greatly hindered by the low yields from its native producers. Here, we developed an orthogonal transcription system, leveraging extra-cytoplasmic function (ECF) sigma (σ) factor 17 … WebApr 1, 2012 · B. subtilis encodes seven ECF σ factors that respond to various cell envelope stresses. With respect to molecular mechanisms involved in σ factor activation the most well studied B. subtilis ECF σ factors is σ W.Expression of sigW is induced by a number of different extracellular stresses including alkaline stress, peptidoglycan stress (cell wall … jefe custom
Structural basis of ECF-σ-factor-dependent transcription initiation
WebMar 3, 2009 · Although no gene encoding a putative ECF sigma factor could be detected in the phyR genomic region in M. extorquens AM1, the complete genome sequence indicated the presence of several genes encoding putative ECF sigma factors. Thus, we pursued the possibility that an ECF sigma factor could be responsible for PhyR-dependent stress … Webencode closely related sigma factors (sequences updated in Table 2). All these sE homologues seem to function in response to events occurring in the extracytoplasm and Lonetto et al. (1994) designated this group as the extra-cytoplasmic function sigma factor, or ECF subfamily. The different sequences of the known sE homologues WebNov 18, 2002 · Functional model of ECF factor. The model depicts the sequestration of the ECF σ factor by its cognate anti-sigma factor. The existence of such an interaction has been demonstrated either biochemically or genetically for E. coli (3; 20), P. aeruginosa (23; 27), Photobacterium sp. and M. xanthus . lagu rohani daerah papua
