Biochemical analyses show that mitochondrial COX16 assists in the process of copper insertion into COX2 and reveal a second COX16 function in linking assembly routes of the redox center-containing COX1 and COX2 subunits.
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.
Exploring natural Hsp104 variation reveals unexpected tuning of a passive activity that inhibits aggregation of specific substrates to selectively counter TDP-43 or alpha-synuclein proteotoxicity connected to neurodegenerative disease.
A new class of fungal hemoproteins is described that emphasizes the versatility of the Sec14-fold for translating binding of chemically distinct ligands to control of diverse sets of cellular activities.
Glycosylation of flagellins with pseudaminic acid in the bacterial cytoplasm governed by an unknown type of modular glycosyltransferase harboring an N-terminal substrate binding domain and a C-terminal glycosyltransferase domain.
