Disulfide bonds as switches for protein function.
The prevailing view is that disulfide bonds have been added during evolution to enhance the stability of proteins that function in a fluctuating cellular environment. However, recent evidence indicates that disulfide bonds can be more than inert structural motifs. The function of some secreted soluble proteins and cell-surface receptors is controlled by cleavage of one or more of their disulfid...
متن کاملFunctionalization of carbon nanotubes via cleavable disulfide bonds for efficient intracellular delivery of siRNA and potent gene silencing.
We present a novel functionalization scheme for single-walled carbon nanotubes (SWNTs) to afford nanotube-biomolecule conjugates with the incorporation of cleavable bonds to enable controlled molecular releasing from nanotube surfaces, thus creating "smart" nanomaterials with high potential for chemical and biological applications. With this versatile functionalization, we demonstrate transport...
متن کاملEnhancing protein stability with extended disulfide bonds.
Disulfide bonds play an important role in protein folding and stability. However, the cross-linking of sites within proteins by cysteine disulfides has significant distance and dihedral angle constraints. Here we report the genetic encoding of noncanonical amino acids containing long side-chain thiols that are readily incorporated into both bacterial and mammalian proteins in good yields and wi...
متن کاملDisulfide bonds are generated by quinone reduction.
The chemistry of disulfide exchange in biological systems is well studied. However, very little information is available concerning the actual origin of disulfide bonds. Here we show that DsbB, a protein required for disulfide bond formation in vivo, uses the oxidizing power of quinones to generate disulfides de novo. This is a novel catalytic activity, which to our knowledge has not yet been d...
متن کاملProfile of the disulfide bonds in acetylcholinesterase.
The inter- and intrasubunit disulfide bridges for the 11 S form of acetylcholinesterase isolated from Torpedo californica have been identified. Localized within the basal lamina of the synapse, the dimensionally asymmetric forms of acetylcholinesterase contain either two (13 S) or three (17 S) sets of catalytic subunits linked to collagenous and noncollagenous structural subunits. Limited prote...
