objects you can drag to a maquettewindow, or you can input to a maquette icon): The classes of objects recognizedby the maquette (i.e. Or by simply opening the maquette editor by double-clicking the maquette icon and dragging objects in, from the OM Workspace, from patches, or from the finder itself. First by using the maquette module addbox2maquette. Otherways of filling the maquette are possible: On the rightmost input you'llconnect a list of objects acceptable by the maquette. On the leftmost input, you'llconnect a list of time offsets.
DEFINE MAQUETTE PATCH
(Note: Abstracted patchesor maquettes may only be inside a patch and not on theWorkspace.). One cantransform ('abstract') a maquette into an 'internal' oneby selecting its icon and clicking-a on the keyboard if and onlyif the maquette is inside a patch.
The difference between these two kinds of maquetteis that the internal maquette has no attachment and cannotbe called directly from a Workspace but exclusively from withina patch by command-click-drag and typing the name 'maquette'.For instance, if you drag a maquette from a Workspace intoa patch, the dragged maquette will reflect any changesdone within its sister maquette and vice versa. It is also possible to call an 'internal' maquette (red maquette) which is the equivalentof a red Patch. maquettescan be dragged into a patch window, where they come equipped withone output and two inputs. maquettesicons are created on the Workspace through the command 'New maquette'in the Filemenu or by the shortcut command-2. A minimal protein environment around the unique Fe (large maroon sphere) and the tertiary N (large blue sphere) of the cluster and the SAM cofactor, respectively, of a radical SAM metalloenzyme.A maquette can be thoughtof as a special patch where a time dimension appears. Using the Protein Databank, we map out the most essential intramolecular interactions that define the minimal structural unit to house a redox active cluster coordinated with the SAM cofactor. Eric Boyd’s GeoBiology laboratory at Montana State University, we investigate the radical SAM metalloenzyme’s cluster binding Cx 3Cx 2C motif, and compare and contrast it to bacterial ferredoxin Cx 2Cx 2C motifs to gain insights into the evolution of motif composition and emergence of chemical function.
DEFINE MAQUETTE FULL
Given the size and composition of the full -peptide maquette, we are developing integrated QM/MM models to describe both the electronic and magnetic structure of the cluster as well as the conformational flexibility of the peptide with or without the cluster present. We utilize spectroscopically validated levels of theory and pay extra attention to realistic representation of solvation in structure, enthalpies, and entropies.
We take advantage of the full repertoire of computational chemistry tools from empirical force field methods, semi-empirical MO and DFT parameter sets, and ab initio MO and DFT calculations. All our experiments indicate that the 2+ cluster reduction is a one-electron process that is accompanied by cluster decomposition and reassembly process at the + oxidation level. The one-electron reduced form, however, persists in lower amounts our data suggest this is not a simple A -> B one-electron process. The as isolated or oxidized form of the maquette is obtained in relatively high yields.
We have established a robust synthetic approach to reproducibly and in high yield prepare maquettes using a wide range of short oligopeptides with varying sequence composition. Below you can find a few highlights about the current research activities. The students can customize their research training depending on their interests and needs to solve chemical problems, such as defining structure/function relationships of clusters, exploring their evolutionary role, interrogating their reactivity, and developing new theoretical methods and experimental techniques to study them. The Fe-S maquette chemistry in our laboratories build on the synergistic application of chemical Synthesis, computational Theory, and analytical Measurements (STM).
