Continuous labelling of callus with H-thymidine results in intermittent peaks of H-DNA per chloroplast, showing synchrony of division. The increase in H-DNA could be due to several replication rounds, and the drop to successive plastid divisions without intervening DNA synthesis. The level of DNA-binding proteins in the chloroplast parallels the peaks of plastidal DNA synthesis; such pro...

in the near future, design of a new generation of drugs targeting proteins will be required. considering the complex bond between the drug and protein, the structure and stability of the target protein should be considered. so far, a series of in vitro investigations have been conducted with the aim of predicting drug-biological medium interactions. in these studies, use of spectroscopic method...

The cowpea weevil (Callosobruchus maculatus) is the main pest that attacks (Vigna unguiculata) seeds during storage, causing nutritional and economic losses in crop. Thus, studies aiming to identify resistant cultivars have been developed. Chitin-binding proteins (CBP), such vicilins chitinases, detected related with toxicity insects. In this work, we investigated presence of chitin-binding par...

Objective(s): The periodic binding of protein expressed by Mycobacterium tuberculosis H37Rv with the host cell receptor molecules i.e. fibronectin (Fn) is gaining significance because of its adhesive properties.  The genome sequencing of M. tuberculosis H37Rv revealed that the proline-glutamic (PE) proteins contain polymorphic GC-rich repetitive sequences (PGRS) which have clinical importance i...

Mutations in the ergosterol biosynthesis gene 11 (ERG11) of Candida albicans have been frequently reported in fluconazole-resistant clinical isolates. Exploring the mutations and their effect could provide new insights into the underlying mechanism of fluconazole resistance.  Erg11p_Threonine285Alanine (Erg11p_THR285ALA), Erg11p_Leucine321Phenylalanine (Erg11p_LEU321PHE) and Erg11p_Serine457Pro...

the aim of this study was to evaluate the sensitivity of the population of fez and casablanca in morocco to dry white beans (phaseolus vulgaris) and to investigate the effect of food processing (heat and/or enzymatic hydrolysis by pepsin) on this sensitivity. work was based on a bank consisting of 146 sera from patients with atopic hypersensitivity in order to evaluate specific immunoglobulin e...

the binding of drugs by plasma proteins is an important phenomenon, because it influences the size of the free fraction of the drugs in plasma. in this study the influence of dipyridamole (dp) on the protein binding of propranolol (pl) and pl on the protein binding of dp were studied alone and in the presence of nicotine (nc).        the equilibrium dialysis was employed for protein binding stu...

Summary Proteins are known to undergo structural changes upon binding partner proteins. However, the prevalence, extent, location, and function of change in protein dynamics due transient protein-protein interactions is not well documented. Here, we have analyzed a dataset 58 complexes three-dimensional structure structures their corresponding unbound forms evaluate induced by binding....
