A fungal effector secreted by the corn smut pathogen increases the virulence of the pathogen by elevating anthocyanin production and reducing lignification in maize.
Fluorescent sensors for the hormone abscisic acid have been developed using a high-throughput platform, and used to monitor hormone dynamics in plant roots and leaves.
Translation quality control protects the cell from environmental stresses that could potentially lead to the toxic accumulation of non-proteinogenic amino acids in the proteome.
Direct modification by endogenous peroxide of a conserved cysteine in the molecular chaperone BiP decouples its ATPase and peptide-binding activities, allowing for enhanced polypeptide holdase activity during oxidative stress.
High affinity interactions with transport adaptors are important to shield the interaction surfaces of cytomatrix components to block fatal premature oligomerization of active zone proteins during axonal transport.
A eukaryotic cell model overcomes metabolic deficiencies within a complex, self-establishing community that enables the growth-relevant exchange of metabolic intermediates.
A canonical class III adenylate cyclase with a membrane anchor of six transmembrane spans is regulated by a receptor of similar design, the quorum-sensing receptor from Vibrio harveyi.
Weak yet highly species-specific protein-protein interactions enhance the activity of metabolically related enzymes in bacteria at endogenous conditions, but also mean that overexpression of one partner leads to permanent non-physiological complexes and gene dosage toxicity.
