  • How BamA recruits OMP substrates via poly‐POTRAs

    2019-11-8 · The E. coli BAM is one of the most studied systems. In E. coli, BamA and BamD are the essential components for the assembly of OMPs (6, 16). In comparison, the other components, which might contribute to the overall function and assembly of BAM complex, are less critical (7, 9, 17).

    2021-6-8 · Chaperone-defective E. coli cells can abort translation of misfolded polypeptides. The non-canonical release factor RF3 recognizes aberrant nascent chains and is recruited to the ribosome, where it cooperates with RF2 in terminating translation. This function is critical for proteostasis maintenance.

The ab initio model-determination program GASBOR [] was used to reconstruct the models of wild-type and mutant E. coli PmrD in solution. The reconstructed models were obtained without imposing any symmetry restrictions, and were averaged using DAMAVER [].The atomic coordinates of the …

    2018-9-13 · Microbial community structure and function rely on complex interactions whose underlying molecular mechanisms are poorly understood. To investigate these interactions in a simple microbiome, we introduced E. coli into an experimental community based on a cheese rind and identified the differences in E. coli’s genetic requirements for growth in interactive and non-interactive contexts using ...

    generate mutant 4-epimerases that are free of the wild-type contamination, an E. coli host bearing the T7 RNA poly-merase gene for expression of the target protein was needed but the host had to be incapable of generating the wild-type epimerase from its chromosome. To produce a wild-type deficient host, araD-139 E. coli strain B [a gift from N ...

    2020-1-14 · Whereas iron–sulfur (Fe–S) cluster assembly on the wild-type scaffold protein ISCU, as catalyzed by the human cysteine desulfurase complex (NIA)2, exhibits a requirement for frataxin (FXN), in yeast, ISCU variant M108I has been shown to bypass the FXN requirement. Wild-type ISCU populates two interconverting conformational states: one structured and one dynamically disordered. We show …
