HSP70 chaperones play pivotal roles in facilitating protein folding, refolding, and disaggregation through their binding and releasing activities. This intricate process is further supported by J-domain proteins (JDPs), also known as DNAJs or HSP40s, which can be categorized into classes A and B. In yeast, these classes are represented by Ydj1 and Sis1, respectively. While both classes stimulate the ATPase activity of Ssa1 (yeast HSP70) through the J-domain, only class B JDPs possess the unique...
[NMR paper] NMR-Based Characterization of the Interaction between Yeast Oxa1-CTD and Ribosomes
NMR-Based Characterization of the Interaction between Yeast Oxa1-CTD and Ribosomes
In mitochondria, the major subunits of oxidative phosphorylation complexes are translated by the mitochondrial ribosome (mito-ribosome). The correct insertion and assembly of these subunits into the inner mitochondrial membrane (IMM) are facilitated by mitochondrial oxidase assembly protein 1 (Oxa1) during the translation process. This co-translational insertion process involves an association between the mito-ribosome and the C-terminus of Oxa1 (Oxa1-CTD) Nuclear magnetic resonance (NMR)...

[NMR paper] Backbone and sidechain NMR assignments of residues 1-81 from yeast Sis1 in complex with an Hsp70 C-terminal EEVD peptide
Backbone and sidechain NMR assignments of residues 1-81 from yeast Sis1 in complex with an Hsp70 C-terminal EEVD peptide
Molecular chaperones aid proteins to fold and assemble without modifying their final structure, requiring, in several folding processes, the interplay between members of the Hsp70 and Hsp40 families. Here, we report the NMR chemical shift assignments for ¹ H, ^(15) N, and ^(13) C nuclei of the backbone and side chains of the J-domain of the class B Hsp40 from Saccharomyces cerevisiae, Sis1, complexed with the C-terminal EEVD motif of Hsp70. The data revealed information...

[NMR paper] NMR structural analysis of the yeast cytochrome c oxidase subunit Cox13 and its interaction with ATP
NMR structural analysis of the yeast cytochrome c oxidase subunit Cox13 and its interaction with ATP
CONCLUSIONS: Together with functional analysis of purified CytcO, we suggest that this ATP interaction is inhibitory of catalytic activity. Our results shed light on the structural flexibility of an important subunit of yeast CytcO and provide structure-based insight into how ATP could regulate mitochondrial respiration.
