A SecE Mutation That Modulates SecY-SecE Translocase Assembly, Identified as a Specific Suppressor of SecY Defects [PDF]

Journal of Bacteriology, 2003
ABSTRACT The SecY39(Cs) (cold-sensitive) alteration of Arg357 results in a defect of translocation initiation. As a means to dissect the Sec translocation machinery, we isolated mutations that act as suppressors of the secY39 defect.

The secY gene of V. cholerae: identification, cloning and characterization

, 1997
The secY gene of Vibrio cholerae has been cloned and the complete nt sequence determined. It codes for a protein of 438 aa residues which functions as a translocator through which proteins cross the inner membrane.

Comparison of DNA extraction methods for molecular identification of pathogenic Leptospira in the urine samples

Health Science Journal of Indonesia, 2020
Latar belakang: Leptospirosis merupakan zoonosis penting di dunia, yang masih sering terjadi salah diagnosis. Deteksi laboratorium Leptospira menjadi tantangan karena bakterimea cukup singkat untuk dideteksi molekuler, namun antibodi juga muncul sangat ...

Bacterial protein translocation requires only one copy of the SecY complex in vivo [PDF]

, 2012
The transport of proteins across the plasma membrane in bacteria requires a channel formed from the SecY complex, which cooperates with either a translating ribosome in cotranslational translocation or the SecA ATPase in post-translational translocation.

A unified evolutionary origin for the ubiquitous protein transporters SecY and YidC. [PDF]

, 2022
BACKGROUND: Protein transporters translocate hydrophilic segments of polypeptide across hydrophobic cell membranes. Two protein transporters are ubiquitous and date back to the last universal common ancestor: SecY and YidC.

Serovar diversity of pathogenic Leptospira circulating in the French West Indies. [PDF]

PLoS Neglected Tropical Diseases, 2013
BACKGROUND: Leptospirosis is one of the most important neglected tropical bacterial diseases in Latin America and the Caribbean. However, very little is known about the circulating etiological agents of leptospirosis in this region.

Mitogenome structure and phylogenomics of the order Thoreales (Nemaliophycidae, Rhodophyta)

Journal of Phycology, EarlyView.
Abstract Organelle genomes offer a powerful tool for red algal evolutionary studies. Although the number of Rhodophyta genomes has increased substantially over the past 2 decades, only two mitochondrial genomes have been reported for the red algal order Thoreales.

Two-way communication between SecY and SecA suggests a Brownian ratchet mechanism for protein translocation

eLife, 2016
The essential process of protein secretion is achieved by the ubiquitous Sec machinery. In prokaryotes, the drive for translocation comes from ATP hydrolysis by the cytosolic motor-protein SecA, in concert with the proton motive force (PMF). However, the

Structure of the SecY channel during initiation of protein translocation [PDF]

, 2014
Many secretory proteins are targeted by signal sequences to a protein-conducting channel, formed by prokaryotic SecY- or eukaryotic Sec61-complexes, and are translocated across the membrane during their synthesis1,2.

Translokation sekretorischer Proteine durch das Sec61/SecY-Translokon

, 2023
Die Translokation von Proteinen durch die prokaryotische Zytoplasmamembran und die Membran des eukaryotischen Endoplasmatischen Retikulums (ER) ist ein wichtiger Schritt in der Biosynthese sekretorischer Proteine sowie Membranproteinen und erfolgt über ...
