“…As in the case of shape analysis, distances from representative atoms between 15 residues surrounding the pocket were measured to find the best correlation of distances with K d,STU . Multiple linear regression was performed using the program xlstat ( 26 ) to find the best equation relating the distances measured between the centre points near the ends of the side chains (see Appendix S2 ) and log 10 K d,STU . Amino acid residues used to create these distance descriptors were extracted by referring to PKA equivalent residues from the ClustalX ( 27 ) multiple sequence alignment of the 113 kinases in Fabian’s data set ( 12 ).…”

Relationships between ligand binding and the shapes of the binding sites in families of homologous enzymes are investigated by comparing matrices of distances between key binding site atoms. Multiple linear regression is used to help identify key distances that influence ligand binding affinity. In order to illustrate the utility of this generic approach, we study protein kinase binding sites for ATP and the promiscuous competitive inhibitor, staurosporine. We show that the size of the gatekeeper residue and the closure between the first glycine of the GXGXXG motif and the aspartate of the DFG loop act together to promote tight binding. Our web-based tool, ‘mapping analogous hetero-atoms onto residue interactions’ (MAHORI), indicates that the greater the number of hydrogen bonds made by the kinase around the methylamine group of staurosporine, the tighter the binding. The conservation of surrounding atoms identified using our novel grid-based method clearly demonstrates that the most structurally conserved part of the binding site for staurosporine is the main chain of the hinge region. The critical role of interactions that are not dependent on side-chain identities is consistent with the promiscuous nature of this inhibitor.

In this paper, Image recognition is the process of identifying and detecting an object or a feature in a digital image or video. Feature extraction a type of dimensionality reduction that efficiently represents interesting parts of an image as a compact feature vector.A computer revolution has occurred not only in engineering field but also in Medical field, where vast amount of information must be processed very quickly and accurately. High resolution scanning techniques such as digital radiography, tomography, nuclear magnetic resonance, produces an image containing relevant information for medical analysis. The use of computers for handling image data in the healthcare is growing. The amount data produced by modern image generating techniques, such as Computed Tomography (CT) and Magnetic Resonance (MR), is vast. This huge data might be a problem from a storage point of view or when the data is sent over a network. To overcome such problems data compression techniques are needed.

“…Kap. 6 greift in dieser Stoßrichtung Arbeiten auf, die in den IB, vor allen Dingen an den Rändern der Disziplin 38 , durchaus existieren, allerdings eher neben dem, teils in offener Abgrenzung zum mehrheitsfähigen Sozialkonstruktivismus. Attraktiv erscheint bei einigen dieser Arbeiten, dass Prozesse der Bedeutungsschaffung als zentrales Problem ausgemacht werden.…”
