Translocation of nascent non-signal sequence protein in heated Escherichia coli.

Synthesis of Nascent Protein by Ribosomes in Escherichia Coli.

Signal recognition particle (SRP)-mediated targeting and Sec-dependent translocation of an extracellular Escherichia coli protein.

Hemoglobin protease (Hbp) is a hemoglobin-degrading protein that is secreted by a human pathogenic Escherichia coli strain via the autotransporter mechanism. Little is known about the earliest steps in autotransporter secretion, i.e. the targeting to and translocation across the inner membrane. Here, we present evidence that Hbp interacts with the signal recognition particle (SRP) and the Sec-t...

Expression and Secretion of Human Granulocyte Macrophage-Colony Stimulating Factor Using Escherichia coli Enterotoxin I Signal Sequence

With the aim of the secretion of human granulocyte macrophage-colony stimulating factor (hGM-CSF) in Escherichia coli, hGM-CSF cDNA was fused in-frame next to the signal sequence of ST toxin (ST-I) of exteroxigenic E. coli, containing 53 or 19 amino acids of signal peptide. The fused STsig::hGM-CSF coding fragments were inserted into a T7-based expression plasmid. The recombinant plasmids were ...

Advances and challenges in recombinant protein expression in Escherichia coli

Periplasmic expression of Bacillus thermocatenulatus lipase in Escherichia coli in presence of different signal sequences

Efforts to express lipase in the periplasmic space of Escherichia coli have so far been unsuccessful andmost of the expressed recombinant lipases accumulate in the insoluble cell fraction. To evaluate the role ofnative and heterologous signal peptides in translocation of the lipase across the inner membrane of E. coli,the lipase gene (btl2) was cloned downstream of the native ...
