Functional conformation of barnase
WebThese enzymes should be most active when delivered to the cytoplasm, but experimental data demonstrate that barnase in the form of a targeted recombinant protein that binds to the surface HER2 ... WebSep 1, 1998 · Thermal denaturation of binase, barnase and chimeric RNases is a two-state transition. The mutation-induced changes in the free energy of unfolding of barnase deduced from thermal and urea denaturation nearly coincide. The kinetic parameters for GpU and GpC demonstrate that the chimeras fall into two groups: barnase-like and …

WebOct 10, 2013 · Moreover, it may help in the design of thermostable biomolecules that are functional at high temperature. Barnase (E.C.3.1.2.7) is an extracellular 110 residue ribonuclease from Bacillus amyloliquefaciens. It has broad application prospects ... The overall conformation, hydrophobic core compactness, and secondary structural … WebThus, in this study, each module of a protein was synthesized and assessed for functional potentiality. For this purpose, barnase, a bacterial ribonuclease, was decomposed into six modules (M1-M6), which were examined to determine whether they have an affinity for RNA and RNase activity.
WebJan 16, 2004 · Functional activities of the two heterologous modules of the chimeric protein remained unchanged versus individual VL and barnase [18]. Consistent with the functional independence of the two modules of VL-barnase, here we demonstrate their independent folding into a fully compact conformation. WebNov 23, 2003 · The ribonuclease barnase (12 kDa) and its inhibitor barstar (10 kDa) form a very tight complex in which all N and C termini are accessible for fusion. Here we exploit …
WebIts function is to inhibit the ribonuclease activity of its binding partner barnase, with which it forms an extraordinarily tightly bound complex within the cell until barnase is secreted. Expression of barstar is necessary to counter the lethal effect of expressed active barnase. The structure of the barnase-barstar complex is known. WebAug 1, 1999 · Barnase is a single domain RNase consisting of 110 amino acid residues and was decomposed into six modules. We designed a mini-protein by removing the second module, M2, from barnase in order to gain an insight into …
WebWe report in this study, strategies for enhancing and extending tissue-specific expression of a restorer gene (barstar) and their use in the development of improved fertility restorer lines for transgenic male sterile (barnase) lines for hybrid seed production.In the first strategy, a chimeric promoter was developed by combining regulatory elements of two overlapping …
WebMolecular dynamics simulations of barnase unfolding also show that it unfolds at lower forces than proteins with mechanical function. The unfolding pathway involves the unraveling of the protein from the termini, with much more native-like secondary and tertiary structure being retained in the transition state than is observed in simulations of ... official title of uk prime ministerWebFeb 2, 1999 · We describe a crystal form of barnase in which the barnase molecules form a trimer by three-dimensional domain swapping.
