Sep 29, 2021 · MotA/TolQ/ExbB proton channel family. This family groups together integral membrane proteins that appear to be involved translocation of proteins across a membrane. These proteins are probably proton channels. MotA is an essential component of the flageller motor that uses a proton gradient to generate rotational motion in the flageller.

Oct 25, 2021 · Download alignment. TolQ protein. TolQ is one of the essential components of the Tol-Pal system. Together with TolR, it harnesses protonmotive force to energize TolA, which spans the periplasm to reach the complex of TolB and Pal at the outer member. The tol-pal system proves to be important for maintaining outer membrane integrity. The tolQ allele in P90C is tolQ13, an amber mutation in codon 36 of tolQ that has been shown to reduce transcription of tolA by ≈ 50% (Vianney et al., 1996). Thus, the phenotype of the tolQ mutation regarding O7 LPS surface expression can be explained by a polar effect on tolA gene expression.Dec 20, 2021 · The TolQ, R and A proteins are located in the cytoplasmic membrane. The TolQ protein has three membrane-spanning segments which are located in the periplasm. The TolR and TolA are attached with a single transmembrane segment in the cytoplasmic membrane. TolB is a periplasmic protein which is connected with the outer membrane by …

Mar 1, 1999 · TolQ has been tagged with an epitope localized in the N-terminal domain of colicin A and recognized by the 1C11 MAbs . We could not directly detect any EpTolQ-TolR complex upon cross-linking of tolQ cells producing EpTolQ and TolR [TPS13(pEpTolQ, pARTR)] by using the AbTolR antiserum or MAb 1C11 because EpTolQ is produced in insufficient amounts.

ExbB has a band of positive charge in the middle of the chamber followed by a ...TolA, TolQ, and TolR proteins form the IM complex of the Tol–Pal system, a proton motive force (PMF)-dependent molecular motor conserved in gram-negative bacteria (Fig. 1 A). The TolQ–TolR motor is evolutionary related to the ExbB–ExbD motor of the Ton system, which is involved in the active transport of iron siderophores and cobalamin . This complex assembles with a minimal TolQ/TolR ratio of 4:2, therefore involving at least 14 transmembrane helices, which may form the ion pathway. The C-terminal periplasmic domain of TolR protein interacts with TolQ and has been proposed to control the TolQR channel activity.

For this study, the plasmid carrying only tolQ (pRA031) was constructed from pRA003 (carrying both tolQ and tolR) by removal of tolR with specific restriction, followed by ligation. This tolQ construct was then excised by restriction and ligated into the identically restricted pBAD18‐Cm to create pMT002.

Dec 1, 1992 · A new colicin, Col5, was synthesized by an Escherichia coli isolate of human origin from the ECOR Collection. It was unique because it adsorbed to the outer-membrane protein Tsx, but used the tonB rather than the tolQ membrane transport system, which is employed by the only other Tsx-specific colicin, ColK. Col5 was encoded by a 5.2 kb …
