WebFeb 14, 1992 · Abstract. Cysteine and half-cystine in proteins and peptides can be determined by acid hydrolysis in the presence of dithiodiglycolic acid, derivatization with phenyl isothiocyanate, and HPLC separation of the phenylthiocarbamyl amino acids. The determination requires no additional sample handling, oxidation, reduction, alkylation, or … WebAt the DNA level cysteines and half cystines are indistinguishable. Here we show that the sequential environments of 'free' cysteine and half cystine are different. A possible origin of this difference is discussed and a simple method to predict cysteines and half cystines from the amino acid sequence is also presented.",
