Cystine in human serum proteins.
FEW QUANTITATIVE ANALYSES of cystine in human serum protein fractions have been recorded in the literature, since cystine cannot be determined easily by microbiologic assay or paper chromatography. Brand and his coworkers (1, 2, 3) have reported the amount of cystine and cysteine in a few protein fractions using phosphotungstate and iodometric methods, but few results have been given using the ...
متن کاملDetermination of the Tyrosine Content of Proteins
In 1925, I published a method for the quantitative calorimetric determination of tyr0sine.l Up to that time tyrosine had been determined either by actual isolation or by calorimetric procedures that were applied to the crude hydrolysates. The calorimetric procedures employed were not certainly characteristic for tyrosine and reactions that are allowed to proceed in the presence of 95 or more pe...
متن کاملfunctional study of p0 proteins of two cereal yellow dwarf viruses (cydv-rpv and cydv-rps) and identification of their cellular partner
نقش سرکوبگری پروتئین p0 در دو پولروویروس کوتولگی زردی غلات cydv-rpv) و (cydv-rps، متفاوت در شدت بیماریزایی، مورد مطالعه قرار گرفت. نتایج نشان داد که هر دو پروتئین p0 p0cy-rpv) و (p0cy-rps قادر به سرکوب خاموشی آر ان ای ایجاد شده توسط ترادف های تراژن سنس و تکرار معکوس در n. benthamiana هستند. نشان داده شد که هر دو پروتئین p0 می توانند تخریب پروتئین argonaute-1 را تسهیل کنند. علاوه بر این، تمایل م...
A cystine-dependent inactivator of tyrosine aminotransferase co-purifies with gamma-cystathionase (cystine desulfurase).
Tyrosine aminotransferase is stable in homogenates of rat liver, but not when L-cystine or L-cysteine is added, which causes the enzyme to be reversibly inactivated due to oxidation of thiol groups. By monitoring inactivation of the aminotransferase in the presence of L-cystine, a factor responsible for this loss of activity was purified from rat liver. The factor required vitamin B6 and co-pur...
متن کاملFormation of Cystine Slipknots in Dimeric Proteins
We consider mechanical stability of dimeric and monomeric proteins with the cystine knot motif. A structure based dynamical model is used to demonstrate that all dimeric and some monomeric proteins of this kind should have considerable resistance to stretching that is significantly larger than that of titin. The mechanisms of the large mechanostability are elucidated. In most cases, it originat...
