Molecular jamming - the cystine slipknot mechanical clamp in all-atom simulations
, 2011 A recent survey of 17 134 proteins has identified a new class of proteins which are expected to yield stretching induced force-peaks in the range of 1 nN. Such high force peaks should be due to forcing of a slip-loop through a cystine ring, i.e.

The effect of pressure on the crystal structure of hexagonal L-cystine [PDF]
, 2005 The crystal structure of hexagonal L-cystine has been determined at room temperature at pressures between 0.4 and 3.7 GPa; unit-cell dimensions were measured up to 6.4 GPa. The structure of this phase consists of molecules in their zwitterionic form, and

Scaffolding of Cystine‐Stabilized Miniproteins
ChemistrySelect, 2016 AbstractBiomolecular scaffolds were engineered by genetically fusing robust miniproteins in a sequence, like a chain. By fusing these miniprotein chains to a teal fluorescent protein (TFP), an efficient strategy was devised for their production in E. coli.

The electrophoresis of transferrins in urea/polyacrylamide gels [PDF]
, 1980 The denaturation of transferrin by urea has been studied by (a) electrophoresis in polyacrylamide gels incorporating a urea gradient, (b) measurements of the loss in iron-binding capacity and (c) u.v. difference spectrometry. In human serum transferrin

Lysine and methionine + cystine for laying hens during the post-molting phase
Brazilian Journal of Poultry Science, 2012 One experiment was conducted to evaluate the effect of using different lysine and methionine + cystine levels on body weight recovery, performance, and egg quality of laying hens during the post-molting period.

Reversibility of Age-related Oxidized Free NADH Redox States in Alzheimer's Disease Neurons by Imposed External Cys/CySS Redox Shifts. [PDF]
, 2019 Redox systems including extracellular cysteine/cystine (Cys/CySS), intracellular glutathione/oxidized glutathione (GSH/GSSG) and nicotinamide adenine dinucleotide reduced/oxidized forms (NADH/NAD+) are critical for maintaining redox homeostasis. Aging as

Effect of cystine loading and cystine dimethylester on renal brushborder membrane transport
Bioscience Reports, 1990 The effect of loading renal tubule cells with cystine was studied by incubating them with cystine dimethylester. Proline uptake into brushborder membrane vesicles isolated from the cystine loaded cells was not different from that observed into brushborder vesicles isolated from tubules incubated in buffer alone.
