Protein design is a key factor for subunit–subunit association [PDF]
Fundamental questions about role of the quaternary structures are addressed by using a statistical mechanics off-lattice model of a dimer protein. The model, in spite of its simplicity, captures key features of the monomer–monomer interactions revealed by atomic force experiments.

Structural similarity and classification of protein interaction interfaces. [PDF]
Interactions between proteins play a key role in many cellular processes. Studying protein-protein interactions that share similar interaction interfaces may shed light on their evolution and could be helpful in elucidating the mechanisms behind ...

Mitochondrial ribosome assembly in Neurospora. Structural analysis of mature and partially assembled ribosomal subunits by equilibrium centrifugation in CsCl gradients [PDF]
In Neurospora, one protein associated with the mitochondrial small ribosomal subunit (S-5, Mr 52,000) is synthesized intramitochondrially and is assumed to be encoded by mtDNA.

Amino-terminal cysteine residues of RGS16 are required for palmitoylation and modulation of G(i)- and G(q)-mediated signaling [PDF]
RGS proteins (Regulators of G protein Signaling) are a recently discovered family of proteins that accelerate the GTPase activity of heterotrimeric G protein α subunits of the i, q, and 12 classes.

Cloning and Characterization of Protein Prenyltransferase Alpha Subunit in Rice
Protein prenylation plays a crucial role in plant development and stress response. We report the function of prenyltransferase α-subunit in rice. Protein-protein interactions showed that the farnesyl- transferase (OsPFT)/geranylgeranyltransferase-I ...

Picosecond time-resolved fluorescence of phycobiliproteins [PDF]
The α- and β-subunits of C-phycocyanin from Mastigocladus laminosus were prepared according to revised procedures. Both subunits are isolated as dimers, which can be dissociated into monomers with detergent mixtures.

Subunit Exchange in Protein Complexes
Over the past 50 years, protein complexes have been studied with techniques such as X-ray crystallography and electron microscopy, generating images which although detailed are static and homogeneous. More recently, limited application of in vivo fluorescence and other techniques has revealed that many complexes previously thought stable and ...

Characterization of alkali-modified soy protein concentrate [PDF]
To study the influence of the preparation mode, including mild alkali modification, of soy protein concentrate on soluble protein content and composition, some of its nutritive and functional properties were investigated. Soy protein concentrate prepared

Visualization of the exocyst complex dynamics at the plasma membrane of Arabidopsis thaliana [PDF]
The exocyst complex, an effector of Rho and Rab GTPases, is believed to function as an exocytotic vesicle tether at the plasma membrane before soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) complex formation.
