Structure of the SecY Complex Unlocked by a Preprotein Mimic

Cell Reports, 2012
The Sec complex forms the core of a conserved machinery coordinating the passage of proteins across or into biological membranes. The bacterial complex SecYEG interacts with the ATPase SecA or translating ribosomes to translocate secretory and membrane ...

Carbohydrate intake of 10 g/kg body mass rapidly replenishes liver, but not muscle glycogen contents, during 12 h of post‐exercise recovery in well‐trained cyclists

The Journal of Physiology, EarlyView.
Abstract figure legend Exhaustive cycling exercise substantially reduces liver and muscle glycogen stores. During 12 h of post‐exercise recovery without carbohydrate intake, glycogen stores remain depleted. In contrast, when carbohydrate is consumed at 10 g/kg body mass (BM), provided during the first 6 h as sucrose beverages (1.2 g/kg BM/h), liver ...

Tunnel Formation Inferred from the I-Form Structures of the Proton-Driven Protein Secretion Motor SecDF

Cell Reports, 2017
Summary: Protein secretion mediated by SecYEG translocon and SecA ATPase is enhanced by membrane-embedded SecDF by using proton motive force. A previous structural study of SecDF indicated that it comprises 12 transmembrane helices that can conduct ...

Proteomic Analysis of Chloroplast-to-Chromoplast Transition in Tomato Reveals Metabolic Shifts Coupled with Disrupted Thylakoid Biogenesis Machinery and Elevated Energy-Production Components [PDF]

, 2012
A comparative proteomic approach was performed to identify differentially expressed proteins in plastids at three stages of tomato(Solanum lycopersicum) fruit ripening (mature-green, breaker, red). Stringent curation and processing of the data from three

Effects of Probiotic Supplementation on Symptoms and Microbiome Characteristics in Patients With Non‐Celiac Gluten/Wheat Sensitivity: A Randomized Controlled Double‐Blind Trial

Food Frontiers, Volume 7, Issue 2, March 2026.
This randomized, double‐blind, placebo‐controlled trial demonstrated that probiotic supplementation in individuals with non‐celiac gluten/wheat sensitivity improved tolerance to gluten reintroduction in nearly half of participants. The effect was associated with beneficial shifts in gut microbiome composition and function, including enhanced microbial ...

A new MR-SAD algorithm for the automatic building of protein models from low-resolution X-ray data and a poor starting model

IUCrJ, 2018
Determining macromolecular structures from X-ray data with resolution worse than 3 Å remains a challenge. Even if a related starting model is available, its incompleteness or its bias together with a low observation-to-parameter ratio can render the ...

Inter-membrane association of the Sec and BAM translocons for bacterial outer-membrane biogenesis

eLife, 2020
The outer-membrane of Gram-negative bacteria is critical for surface adhesion, pathogenicity, antibiotic resistance and survival. The major constituent – hydrophobic β-barrel Outer-Membrane Proteins (OMPs) – are first secreted across the inner-membrane ...
