1P067 Reduction of metalloproteins by tyrosine-containing oligopeptides

Hg-Coordination Studies of Cysteine Containing Oligopeptides *

In order to study the interaction of cysteine containing peptide chains with Hg(II) the nuclear quadrupole interaction (NQI) of 1 9 9 m Hg in the Hg complex of the oligopeptide Alanine-AlanineCysteine-Alanine-Alanine (AACAA) was determined by time differential perturbed angular correlation. Different 1 9 9 m H g N Q I ' s for free and resin-bound A A C A A were obtained. Furthermore, the 1 9 9 ...

Regulation of Apoptosis by Tyrosine-Containing

Metalloproteins Containing Cytochrome, Iron–Sulfur, or Copper Redox Centers

Kinetics of the reduction of metalloproteins by chromous ion (laccase-cytochrome c-plastocyanins-temperature-rate constants).

The reduction of Cu(330) in Rhus vernicifera laccase by chromous ion is 30% faster than reduction of Cu(614) at room temperature [pH 4.8, mu = 0.1 (NaCl)], and two parallel first-order paths, attributed to heterogeneity of the protein, are observed at both wavelengths. The reactions of stellacyanin, spinach and French-bean plastocyanins, and cytochrome c with chromous ion under similar conditio...

Database searches with multiple oligopeptides containing ambiguous residues.

Several techniques in molecular biology frequently yield partial and ambiguous data on genes and gene products. For instance, N-terminal sequence analysis of oligopeptide cleavage products generates this type of sequence data. Typically, data generated from blotted or HPLC-resolved peptides consist of disconnected and unordered oligopeptides derived from N-terminal analysis of fragments resulti...
