Incubation of whole envelopes prepared from sonically oscillated Escherichia coli K-12 cultures with lysozyme in vitro resulted in the appearance of a protein species with an apparent molecular weight double that of outer membrane protein I. Similar dimers were also detected in purified outer membranes and whole envelopes from lysozyme-induced spheroplasts of E. coli K-12. This was confirmed by...

Cobalt(II)  complexes of isonicotinoyl hydrazones of two series of ligands have been synthesized and characterized on the basis of elemental analyses, molar conductance, magnetic moment, mass, IR, UV spectral data. Electrochemical behavior of ligands and complexes has been investigated by using cyclic voltammetry. Cyclic voltammetric studies reveal that the oxidation/reduct...

Diberikan graf terhubung dan sederhana $G=(V(G), E(G))$ bilangan bulat positif $k$. Himpunan $S \subseteq V(G)$ disebut sebagai pembangkit $k$-metrik jika untuk setiap pasang titik berbeda $u,v \in V(G)$, terdapat paling sedikit $k$ $w_{1}, w_{2}, \ldots, w_{k} S$ sedemikian sehingga $d(u,w_{i}) \neq d(v,w_{i})$ $i \{1,2,\ldots, k\}$, dengan $d(u,v)$ adalah panjang \emph{path} terpendek dari $u...

Cross-linking reagents have been used to link covalently adjacent subunits of solubilized spinach chloroplast coupling factor 1, which is a latent ATPase. 1,5-Difluoro-2,4-dinitrobenzene, dimethyl-3,3'-dithiobispropionimidate, and dimethylsuberimidate are able to form bridges of 3 to 11 A between amino groups, and hydrogen peroxide and the o-phenanthroline-cupric ion complex catalyze the oxidat...

BACKGROUND The aim of this study was to evaluate the protein spots of excretory - secretory products of Fasciola hepatica using two dimension electrophoresis method in the presence and absence of triclabendazole drug which can be considered to detect the target protein of the drug. METHODS F. hepatica parasites were collected from infected cattle livers, divided in two groups and cultivated i...

The quality and ease of proteomics analysis depends on the performance of the analytical tools used, and thus of the performances of the protein separation tools used to deconvolute complex protein samples. Among protein samples, membrane proteins are one of the most difficult sample classes, because of their hydrophobicity and embedment in the lipid bilayers. This review deals with the recent ...
