The homotypic fusion of yeast vacuoles occurs in an ordered cascade of priming, docking, and fusion. The linkage between these steps has so far remained unclear. We now report that Vam7p (the vacuolar SNAP-23/25 homolog) signals from the cis-SNARE complex to Ypt7p (the vacuolar Rab/Ypt) to initiate the docking process. After Vam7p has been released from the cis-SNARE complex by Sec18p-mediated ...

in today’s competitive word, it is so important to offer a new way in the cycle of production and supply by which the maximum efficiency will be achieved. the problem of applying cross-docking operations in logistics and supply chain network design, as a new and applicable approach, has attracted much attention in both academic and industrial areas. the matter making this strategy be highly wel...

Signal transduction pathways use protein kinases for the modification of protein function by phosphorylation. A major question in the field is how protein kinases achieve the specificity required to regulate multiple cellular functions. Here we review recent studies that illuminate the mechanisms used by three families of Ser/Thr protein kinases to achieve substrate specificity. These kinases r...

The influence of various factors on the accuracy of protein-ligand docking is examined. The factors investigated include the role of a grid representation of protein-ligand interactions, the initial ligand conformation and orientation, the sampling rate of the energy hyper-surface, and the final minimization. A representative docking method is used to study these factors, namely, CDOCKER, a mol...

Docking of the P1 duplex into the pre-folded core of the Tetrahymena group I ribozyme exemplifies the formation of tertiary interactions in the context of a complex, structured RNA. We have applied Phi-analysis to P1 docking, which compares the effects of modifications on the rate constant for docking (k(dock)) with the effects on the docking equilibrium (K(dock)). To accomplish this we used a ...

Molecular docking software is mainly used in drug development. offers a wide range of useful techniques for the creation and analysis pharmaceuticals. Before now, predicting target receptor was extremely challenging however, protein with ligand straightforward dependable procedure presently binding affinity designed. To see molecule's three-dimensional structure, variety tools have been created...

Human papillomaviruses (HPV) are a group of strong human carcinogen viruses considered to be the fourth leading cause of mortality among women in the world. HPV is the most important cause of cervical cancer, which is the second most common cancer in women living in low and middle-income countries. To date, there is no effective cure for an ongoing HPV infection; therefore, it is required to in...

Background and Purpose: Soleshine is a polyherbal preparation established in the market for the treatment of cracks and tinea pedis, which is applied externally. This preparation is composed of the extracts of indigenous plants, namely Azadirachta indica, Lawsonia alba, and Shorea robusta, mixed with castor oil and sesame oil. In the present study, an attempt was made to identify the constituen...

Hsp90 is a major protein involved in the stabilization of various proteins in cancer cells. The present investigation focused on the molecular docking simulation studies of flavanols as inhibitors of Hsp90 at the high affinity adenosine triphosphate (ATP) binding site and analyzed absorption, distribution, metabolism, excretion and toxicity (ADME-toxicity). The molecular docking analysis reveal...

monoamine oxidase (ec, 1.4.3.4) or amine oxidoreductase catalyzes the oxidative deamination of biogenic amines. abnormal action of the monoamine oxidase b has been associated with neurological dysfunctions including parkinson´s disorder. monoamine oxidase b inhibitors divulged that these agents were effective in the therapeutic management of parkinson's disease. understanding the interaction of...
