The very early evolution of protein translocation across membranes.

open access: yesPLoS Computational Biology, 2021
In this study, we used a computational approach to investigate the early evolutionary history of a system of proteins that, together, embed and translocate other proteins across cell membranes.

Selenium Biofortification of Solanum Vegetables Modulates Their Phytoconstituents, Agronomic and Antioxidant Properties

open access: yesFood Chemistry International, Volume 1, Issue 4, Page 425-436, December 2025.
Selenium biofortification increases Se concentration in the leaves of the African eggplant and black nightshade leaves. This leads to an alteration in mineral composition in these leaves. ABSTRACT Selenium biofortification of food crops is a method of ameliorating selenium deficiency in a population.

Protein Translocation Is Mediated by Oligomers of the SecY Complex with One SecY Copy Forming the Channel [PDF]

open access: yesCell, 2007
Many proteins are translocated across the bacterial plasma membrane by the interplay of the cytoplasmic ATPase SecA with a protein-conducting channel, formed from the evolutionarily conserved heterotrimeric SecY complex. Here, we have used purified E. coli components to address the mechanism of translocation.

Metabolic Functions and Mechanisms of Selenium, Selenocysteine, and GPX4 Mediated Immune Regulation Through Autophagy in Solid Tumors

open access: yesFood Science &Nutrition, Volume 13, Issue 12, December 2025.
This paper focuses on selenium, selenocysteine, and GPX4, elaborating on their metabolic functions and mechanisms in mediating immune regulation through autophagy in solid tumors. It explores the characteristics of selenium metabolism in tumors and the roles of related enzymes, providing new directions for cancer treatment.

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

open access: yesJournal 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.

Protein translocation:what’s the problem? [PDF]

open access: yes, 2016
We came together in Leeds to commemorate and celebrate the life and achievements of Prof. Stephen Baldwin. For many years we, together with Sheena Radford and Roman Tuma (colleagues also of the University of Leeds), have worked together on the problem of

Liebig Review: Legume–Rhizobium Symbiosis Under Selenium Fertilization: A Unique Dual Function in the Plant–Soil System

open access: yesJournal of Plant Nutrition and Soil Science, Volume 188, Issue 6, Page 861-872, December 2025.
ABSTRACT Background Selenium (Se) plays a vital role as a beneficial element in promoting the production of leguminous plants. It influences legume quality by improving crop nutritive value and contributing to human and animal health. Literature Review This review is timely, as there are gaps in understanding Se–rhizobia interactions in legumes, which ...

Thylakoid protein FPB1 synergistically cooperates with PAM68 to promote CP47 biogenesis and Photosystem II assembly

open access: yesNature Communications
In chloroplasts, insertion of proteins with multiple transmembrane domains (TMDs) into thylakoid membranes usually occurs in a co-translational manner.
