CHAPTER 1.1. Disulfide Bonds in Protein Folding and Stability [PDF]
Disulfide bonds are unique among post-translational modifications, as they add covalent crosslinks to the polypeptide chain. Accordingly, they can exert pronounced effects on protein folding and stability. This is of particular importance for secreted or

Domain discovery method for topological profile searches in protein structures [PDF]
We describe a method for automated domain discovery for topological profile searches in protein structures. The method is used in a system TOPStructure for fast prediction of CATH classification for protein structures (given as PDB files).

Watching G proteins at work [PDF]
It has been known for over a century that rod photoreceptors in the living retina contract and swell in response to light. Although it is still not known whether this structural light-response is of any functional significance, it has recently been possible to correlate the underlying molecular processes with the activation and deactivation of the ...

The G protein γ subunit SlGGC1 regulates saline-alkali stress response in tomato
Saline-alkali stress poses a severe threat to crop yield and quality. While significant progress has been achieved in elucidating the mechanisms of plant resistance to salt stress, the molecular underpinnings governing plant responses to saline-alkali ...

Expressed protein ligation for a large dimeric protein [PDF]
Expressed protein ligation (EPL) is a protein engineering tool for post-translational ligation of protein or peptide fragments. This technique allows modification of specific parts of proteins, opening possibilities for incorporating probes for ...

Heterotrimeric G-Protein Signalers and RGSs in Aspergillus fumigatus
The heterotrimeric G-protein (G-protein) signaling pathway is one of the most important signaling pathways that transmit external signals into the inside of the cell, triggering appropriate biological responses. The external signals are sensed by various
