Minimizing a binding domain from protein A.
We present a systematic approach to minimizing the Z-domain of protein A, a three-helix bundle (59 residues total) that binds tightly (Kd = 10 nM) to the Fc portion of an immunoglobin IgG1. Despite the fact that all the contacts seen in the x-ray structure of the complex with the IgG are derived from residues in the first two helices, when helix 3 is deleted, binding affinity is reduced > 10(5)...
متن کاملConstruction of a New Fusion Protein Vector Associated to Fibronectin Binding Protein A and Clumping Factor A Derived from Staphylococcus aureus NCTC8325
Objective(s) Staphylococcus aureus is a leading cause of many nosocomial and community acquired infections. According to many reports, antibiotic therapy can not guarantee the eradication of S. aureus infections. Thus designing an adhesin based vaccine could restrain the S. aureus infections. This study designed for construction of a new fusion protein vaccine against S. aureus infections base...
متن کاملf/sla from learner perspectives: a social activity or a cognitive process
in the past couple of decades sociocultural theory of sla and its implications in efl contexts have attracted attentions of research circles worldwide and aroused some controversies. firth and wagner (1997) have questioned the principles of the cognitive view which gives importance to mental constructs in favor of sociocultural view which highlights social and contextual constructs. but if soci...
15 صفحه اولSilver Resistance In Acinetobacter baumannii BL54 Occurs Through Binding to a Ag-Binding Protein
The mechanism of plasmid mediated silver (Ag) resistance was investigated in Acinetobacter baumanniiBL54. The intracellular accumulation of Ag in both original strain BL54 and Escherichia coli K12transconjugant containing plasmid pUPI276 began immediately and reached a maximum within 60 minutes.This initial accumulation was followed by net loss of Ag which reached a maximum wi...
متن کاملComparative Investigation of R213G Mutation in DNA-Binding Domain of P53 Protein via Molecular Dynamics Simulation
Introduction: P53 is a tumor suppressor protein with numerous missense mutations identified in its gene. These mutations are observed in a vast number of cancers. R213G is one of them which has a role in metastatic lung cancers. In this research, R213G was studied in comparison with the wild type via molecular dynamics simulation. Method: For the three-dimensional structure of the wild-type P53...
