Defining the heterogeneous composition of Arabidopsis thylakoid membrane

The Plant Journal, Volume 121, Issue 3, February 2025.
Significance Statement Thylakoid membrane of flowering plants exhibits extreme heterogeneity in function, biogenesis, assembly and repair, as well as in the localization of proteins and protein complexes in appressed grana, unstacked stroma lamellae (SL), connecting (CD) and curvature domains.

Privileged proteins with a second residence: dual targeting and conditional re‐routing of mitochondrial proteins

The FEBS Journal, Volume 291, Issue 24, Page 5379-5393, December 2024.
The term dual localization or dual targeting refers to proteins that reside in more than one cellular compartment. Many mitochondrial proteins are dually localized and populate, in addition to mitochondria, the cytosol, the nucleoplasm, chloroplasts, and other compartments.

Hydrophilic microenvironment required for the channel-independent insertase function of YidC protein [PDF]

Proceedings of the National Academy of Sciences, 2015
Significance How membrane proteins are guided into the membrane is a fundamental question of cell biology. Translocons are known to create a polypeptide-conducting transmembrane (TM) channel having a lateral gate to allow lipid-phase partitioning of the substrate.

Differential Modes of Orphan Subunit Recognition for the WRB/CAML Complex

Cell Reports, 2020
Summary: A large proportion of membrane proteins must be assembled into oligomeric complexes for function. How this process occurs is poorly understood, but it is clear that complex assembly must be tightly regulated to avoid accumulation of orphan ...

The Fe Protein: An Unsung Hero of Nitrogenase

Inorganics, 2018
Although the nitrogen-fixing enzyme nitrogenase critically requires both a reductase component (Fe protein) and a catalytic component, considerably more work has focused on the latter species.

The contribution of mRNA targeting to spatial protein localization in bacteria

The FEBS Journal, Volume 291, Issue 21, Page 4639-4659, November 2024.
mRNA‐based targeting serves as a back‐up strategy for the canonical signal sequence‐based protein targeting in bacteria. While signal sequence‐based targeting depends on dedicated protein‐targeting factors, mRNAs encoding inner membrane proteins can bind directly to protein translocases.

Crystal structure of Escherichia coli YidC, a membrane protein chaperone and insertase [PDF]

Scientific Reports, 2014
Bacterial YidC, an evolutionally conserved membrane protein, functions as a membrane protein chaperone in cooperation with the Sec translocon and as an independent insertase for membrane proteins. In Gram-negative bacteria, the transmembrane and periplasmic regions of YidC interact with the Sec proteins, forming a multi-protein complex for Sec ...

Geranylgeranylated‐chlorophyll‐protein complexes in lhl3 mutant of the green alga Chlamydomonas reinhardtii

The Plant Journal, Volume 120, Issue 4, Page 1577-1590, November 2024.
Significance Statement One of the latest steps of chlorophyll synthesis is the hydrogenation of geranylgeranyl chlorophylls (ChlsGG) to phytylated chlorophylls (Chls) by geranylgeranyl reductase (GGR). We have isolated a pale green mutant, which is unable to grow photoautotrophically and accumulates ChlsGG, from the green alga Chlamydomonas reinhardtii.
