Functional Interaction Between Toc75 POTRA1 Domain and Tic22‐III in the Intermembrane Space During Chloroplast Protein Import

open access: yesPlant Direct, Volume 10, Issue 2, February 2026.
ABSTRACT Chaperones are essential for facilitating the import of nuclear‐encoded precursor proteins into chloroplasts. In the intermembrane space (IMS) of the chloroplasts, this process is mediated by the transport‐associated domains (POTRA) of the translocon at the outer envelope membrane (Toc75) and translocon at the inner envelope membrane (Tic22 ...

Ycf93 (Orf105), a small apicoplast-encoded membrane protein in the relict plastid of the malaria parasite Plasmodium falciparum that is conserved in Apicomplexa.

open access: yesPLoS ONE, 2014
Malaria parasites retain a relict plastid (apicoplast) from a photosynthetic ancestor shared with dinoflagellate algae. The apicoplast is a useful drug target; blocking housekeeping pathways such as genome replication and translation in the organelle ...

Roles of Ferredoxin-Dependent Proteins in the Apicoplast of Plasmodium falciparum Parasites

open access: yesmBio, 2022
Ferredoxin (Fd) and ferredoxin-NADP+ reductase (FNR) form a redox system that is hypothesized to play a central role in the maintenance and function of the apicoplast organelle of malaria parasites.

Imaging malaria parasites across scales and time

open access: yesJournal of Microscopy, Volume 301, Issue 2, Page 122-150, February 2026.
Abstract The idea that disease is caused at the cellular level is so fundamental to us that we might forget the critical role microscopy played in generating and developing this insight. Visually identifying diseased or infected cells lays the foundation for any effort to curb human pathology.

Optimisation of freeze substitution protocols for the examination of malaria parasite structure by volumetric electron microscopy

open access: yesJournal of Microscopy, Volume 301, Issue 2, Page 168-186, February 2026.
Abstract Malaria is one of the deadliest infectious diseases in the world, annually responsible for over 400,000 deaths. It is caused by parasites of the genus Plasmodium, which undergo remarkable structural changes during their development within different cells across various hosts.

Transcriptomic analysis of apicoplast-disrupted parasites.

open access: yes, 2020
A) Hierarchical clustering of apicoplast genome expression from control and apicoplast-disrupted parasites during the IDC. The apicoplast gene expression data were normalized by the median expression of 5851 genes from corresponding parasites at each ...

4‐nitrobenzoate inhibits 4‐hydroxybenzoate polyprenyltransferase in malaria parasites and enhances atovaquone efficacy

open access: yesFEBS Letters, Volume 600, Issue 2, Page 251-266, January 2026.
Atovaquone is an antimalarial requiring potentiation for sufficient efficacy. We pursued strategies to enhance its activity, showing that 4‐nitrobenzoate inhibits 4‐hydroxybenzoate polyprenyltransferase, decreasing ubiquinone biosynthesis. Since atovaquone competes with ubiquinol in mitochondria, 4‐nitrobenzoate facilitates its action, potentiating ...

Evolutionary Pressures on Apicoplast Transit Peptides [PDF]

open access: yesMolecular Biology and Evolution, 2004
Malaria parasites (species of the genus Plasmodium) harbor a relict chloroplast (the apicoplast) that is the target of novel antimalarials. Numerous nuclear-encoded proteins are translocated into the apicoplast courtesy of a bipartite N-terminal extension.

Comparative analysis of apicoplast genomes of Babesia infective to small ruminants in China

open access: yesParasites & Vectors, 2019
Background Babesiosis is an economically important disease caused by tick-borne apicomplexan protists of the genus Babesia. Most apicomplexan parasites, including Babesia, have a plastid-derived organelle termed an apicoplast, which is involved in ...

The NTP generating activity of pyruvate kinase II is critical for apicoplast maintenance in Plasmodium falciparum

open access: yeseLife, 2020
The apicoplast of Plasmodium falciparum parasites is believed to rely on the import of three-carbon phosphate compounds for use in organelle anabolic pathways, in addition to the generation of energy and reducing power within the organelle.
