Contribution of UbrA, a ubiquitin ligase essential for Arg/N-degron pathway, to peptidase gene expression in Aspergillus oryzae [PDF]

open access: yesApplied and Environmental Microbiology
The degradation of intracellular proteins by N-degron pathways depends on their N-terminal amino acids. In budding yeast, the Arg/N-degron pathway controls the expression of dipeptide/tripeptide transporter gene by degrading a transcriptional repressor ...

A 1-aminocyclopropane-1-carboxylic-acid (ACC) dipeptide elicits ethylene responses through ACC-oxidase mediated substrate promiscuity

open access: yesFrontiers in Plant Science, 2022
Plants produce the volatile hormone ethylene to regulate many developmental processes and to deal with (a)biotic stressors. In seed plants, ethylene is synthesized from 1-aminocyclopropane-1-carboxylic acid (ACC) by the dedicated enzyme ACC oxidase (ACO).
