Invertases catalyse the conversion of sucrose into glucose and fructose. In plants, invertases fall into two clades – the mitochondrially/plastid localized α clade and the cytoplasmically localized β clade. However, we do not fully understand how these clades evolved. Here Wan et al. identified 665…

Niehaus et al. explore the nucleotide metabolome of germinating seeds By Markus Niehaus1, Henryk Straube1 and Marco Herde1 1Leibniz Universität Hannover, Department of Molecular Nutrition and Biochemistry of Plants Background: All living organisms, including plants, possess DNA and rely on…

The ribosome is a macromolecular structure made up of many subunits. The proteins in these subunits were named based on their sedimentation rates and gel mobility, but different groups gave the proteins different names in various species, not based on homology. A ribosomal protein (r-protein) nomenclature…

Ribosomes are essential molecular machines in the cell that translate mRNA sequences into proteins. Growing parts of an organism produce many ribosomes, so that after each cell division both daughter cells have enough to translate the proteins necessary for growth and development. Defects in ribosomes…

Does a new job always come with a new location? Perhaps this is true for some plant proteins; half of the proteins are located in more than one subcellular compartment. Emerging evidence in plants shows that nuclear-encoded proteins undergo redox and posttranslational modifications or processing events…

It's not just human relationships that may require a chaperone to prevent inappropriate interactions. Numerous proteins in organisms from Escherichia coli to us, especially hydrophobic membrane proteins, also require chaperones in aqueous environments to prevent inappropriate interactions such as aggregation…
