Nucleotide sequence of the secA gene and secA(Ts) mutations preventing protein export in Escherichia coli [PDF]

Journal of Bacteriology, 1988
The DNA sequence of the secA gene, essential for protein export in Escherichia coli, was determined and found to encode a hydrophilic protein of 901 amino acid residues with a predicted molecular weight of 101,902, consistent with its previously determined size and subcellular location.

Cloning and Expression Analysis of Phytoplasma Protein Translocation Genes

Molecular Plant-Microbe Interactions, 2001
Genes encoding SecA and SecY proteins, essential components of the Sec protein translocation system, were cloned from onion yellows phytoplasma, an unculturable plant pathogenic bacterium. The secA gene consists of 2,505 nucleotides encoding an 835 amino

In Vitro Interaction of the Housekeeping SecA1 with the Accessory SecA2 Protein of Mycobacterium tuberculosis. [PDF]

PLoS ONE, 2015
The majority of proteins that are secreted across the bacterial cytoplasmic membrane leave the cell via the Sec pathway, which in its minimal form consists of the dimeric ATP-driven motor protein SecA that associates with the protein-conducting membrane ...

Multiple SecA protein isoforms in Escherichia coli [PDF]

Journal of Bacteriology, 1987
To define the anti-SecA-LacZ antiserum, immunoprecipitates produced with either whole anti-SecA-LacZ rabbit antiserum or affinity-purified antibodies were used to analyze nondenatured lysates of Escherichia coli. The antiserum contains antibodies that recognize different proteins.

The C-terminal tail of the bacterial translocation ATPase SecA modulates its activity

eLife, 2019
In bacteria, the translocation of proteins across the cytoplasmic membrane by the Sec machinery requires the ATPase SecA. SecA binds ribosomes and recognises nascent substrate proteins, but the molecular mechanism of nascent substrate recognition is ...

Mobility of the SecA 2-helix-finger is not essential for polypeptide translocation via the SecYEG complex [PDF]

, 2012
The bacterial ATPase SecA and protein channel complex SecYEG form the core of an essential protein translocation machinery. The nature of the conformational changes induced by each stage of the hydrolytic cycle of ATP and how they are coupled to protein ...

Conformational Dynamics of the Plug Domain of the SecYEG Protein-conducting Channel [PDF]

, 2011
The central pore of the SecYEG preprotein-conducting channel is closed at the periplasmic face of the membrane by a plug domain. To study its conformational dynamics, the plug was labeled site-specifically with an environment-sensitive fluorophore.

SecY and SecA interact to allow SecA insertion and protein translocation across the Escherichia coli plasma membrane [PDF]

The EMBO Journal, 1997
SecA, the preprotein-driving ATPase in Escherichia coli, was shown previously to insert deeply into the plasma membrane in the presence of ATP and a preprotein; this movement of SecA was proposed to be mechanistically coupled with preprotein translocation.

Voltage Sensing in Bacterial Protein Translocation [PDF]

, 2020
The bacterial channel SecYEG efficiently translocates both hydrophobic and hydrophilic proteins across the plasma membrane. Translocating polypeptide chains may dislodge the plug, a half helix that blocks the permeation of small molecules, from its ...

Molecular Mimicry of SecA and Signal Recognition Particle Binding to the Bacterial Ribosome

mBio, 2019
Bacteria execute a variety of protein transport systems for maintaining the proper composition of their different cellular compartments. The SecYEG translocon serves as primary transport channel and is engaged in transporting two different substrate ...
