Evaluation of S-benzyl- L -cysteine-4'-nitroanilide as a substrate for serum cystine aminopeptidase.
Under appropriate conditions, S-benzyl-L-cysteine4’-nitroanilide is rapidly hydrolyzed by serum cystine aminopeptidase. The enzyme may be estimated kinetically by determining the rate of liberation of 4nitroaniline. A simple automated procedure has been devised, and 50 samples of pregnancy sera can be analyzed per hour by use of the LKB 8600 Reaction Rate Analyzer. The correlation coefficient b...
متن کاملHigh-pressure polymorphism in L-cysteine: the crystal structures of L-cysteine-III and L-cysteine-IV.
The crystal structure of the orthorhombic phase of L-cysteine (hereafter L-cysteine-I) consists of chains of molecules linked via NH...O hydrogen bonds. The chains are linked into a layer by other NH...O hydrogen bonds, forming R4(4)(16) ring motifs. The layers are linked by further NH...O and disordered SH...S/SH...O interactions. The main effects of compression to 1.8 GPa are to contract void...
متن کاملProposed conformation of oxytocin in solution.
A conformation of the neurohypophyseal hormone oxytocin in solution is proposed. The structure possesses, in addition to the beta-turn comprised of the sequence -L-tyrosyl-L-isoleucyl-L-glutaminyl-L-asparaginyl- in the ring component of the hormonal molecule, a second beta-turn involving the C-terminal oxytocin sequence, -L-cysteinyl-L-prolyl-L-leucylglycinamide. The resulting oxytocin structur...
متن کاملThe conformation of pyridine dinucleotides in solution.
The dependence of chemical shifts in the nuclear magnetic resonance spectra of pyridine nucleotides on concentration, pH, and temperature has been examined. The data indicate that all of the dinucleotides exist predominantly in a folded conformation, with the planes of the two rings stacked in parallel. The free energy of formation of the intramolecular complexes has been estimated to be of the...
متن کاملThe Decomposition of Cysteine in Aqueous Solution*
In a recent study (1) it was shown that cystine could be decomposed by boiling distilled water with the formation of cysteine, hydrogen sulfide, and elementary sulfur. The decomposition of cysteine under similar conditions should aid in a clearer explanation of the mechanisms involved in the breakdown of these two amino acids. The action of alkaline reagents on cysteine and its derivatives has ...
