Protein import into plant mitochondria [PDF]

open access: yesPlant Molecular Biology, 1997
The presence of plastids in plant cells requires a higher level of precursor recognition by the mitochondrial protein import apparatus than in nonplant organisms. Although the plant presequences display the overall features observed in yeast and mammals, they are generally longer and more hydrophilic.

Deciphering TAL effectors for 5-methylcytosine and 5-hydroxymethylcytosine recognition

open access: yesNature Communications, 2017
Transcription activator-like effector proteins recognise specific DNA sequences via tandem repeats. Here the authors demonstrate TALEs can recognise the methylated bases 5mC and 5hmC, enabling them to detect epigenetic modifications.

Plasmodium falciparum has evolved multiple mechanisms to hijack human immunoglobulin M

open access: yesNature Communications, 2023
Plasmodium falciparum causes the most severe malaria in humans. Immunoglobulin M (IgM) serves as the first line of humoral defense against infection and potently activates the complement pathway to facilitate P. falciparum clearance.

Toxic proteins in plants

open access: yesPhytochemistry, 2015
Plants have evolved to synthesize a variety of noxious compounds to cope with unfavorable circumstances, among which a large group of toxic proteins that play a critical role in plant defense against predators and microbes. Up to now, a wide range of harmful proteins have been discovered in different plants, including lectins, ribosome-inactivating ...

Cryo-EM structure of a functional monomeric Photosystem I from Thermosynechococcus elongatus reveals red chlorophyll cluster

open access: yesCommunications Biology, 2021
Çoruh, Frank et al. report the structure of monomeric Photosystem I from cyanobacteria Thermosynechoccocus elongatus BP-1. They assign monomerization-induced loss of red chlorophylls to a cluster of chlorophylls adjacent to PsaX.

Deacetylation of TFEB promotes fibrillar Aβ degradation by upregulating lysosomal biogenesis in microglia

open access: yesProtein & Cell, 2016
Microglia play a pivotal role in clearance of Aβ by degrading them in lysosomes, countering amyloid plaque pathogenesis in Alzheimer’s disease (AD). Recent evidence suggests that lysosomal dysfunction leads to insufficient elimination of toxic protein ...

Plant protein glycosylation [PDF]

open access: yesGlycobiology, 2016
Protein glycosylation is an essential co- and post-translational modification of secretory and membrane proteins in all eukaryotes. The initial steps of N-glycosylation and N-glycan processing are highly conserved between plants, mammals and yeast. In contrast, late N-glycan maturation steps in the Golgi differ significantly in plants giving rise to ...

Pyrazinamide and derivatives block ethylene biosynthesis by inhibiting ACC oxidase

open access: yesNature Communications, 2017
Ethylene is a plant hormone that promotes fruit ripening. Here, the authors identify pyrazinamide, a drug used to treat tuberculosis, as an inhibitor of ethylene biosynthesis inArabidopsis thalianaand present the crystal structure of its active form ...
