The Km is a measure of the binding affinity of an enzyme for its ligand (substrate or cofactor) and is defined as the concentration of ligand required to fill one-half of the ligand-binding sites. From: Molecular Genetics and Metabolism, 2004 ...
(7) in theMethods. In the prediction phase, molecular-pair representations are learned by optimizing the losses of two tasks: (1) the predictions of affinity differences and (2) the probabilities that the affinity of ligandiis greater than that of ligandjby two independent branches of three-...
Binding affinity is the strength of the binding interaction between a single biomolecule (e.g., a protein or DNA) to its ligand or binding partner (e.g., a drug or inhibitor). Binding affinity is typically measured and reported by the equilibrium dissociation constant (KD), which is used ...
4.2.1 Ligand binding assays Ligand binding assays are non-functional tests that detect the binding affinity of a compound to a target (ion channel in this case). These are low-cost screening assays widely used to study ion-channel modulators and measure the ligand's direct interaction with its...
In this study, we evaluate a wide range of ligands for their binding affinity towards the RGD-binding integrins αvβ3, αvβ5, αvβ6, αvβ8, α5β1, αIIbβ3, using homogenous ELISA-like solid phase binding assay. Structural and signalling responses of cells are tightly regulated ...
在药物的图表示中,对节点分配了九个原子特征(Atomic number, Chirality, Atom degree, Formal charge, Total Number of Hs, Radical Electrons, Hybridization, Aromaticity, and In Ring),对边分配了两个键特征(Bond type and Rings),以通过邻接矩阵汇总图并作为输入传递给下一个网络。
developed gCOMBINE [38], a Java graphical user interface (GUI), to perform COMBINE analyses, providing a convenient tool for academic researchers. The key idea of COMBINE analysis is that a simple expression describing the differences in binding affinity of a series of related ligand-receptor ...
Prediction of protein–ligand binding affinity by free energy simulations: assumptions, pitfalls and expectations Many limitations of current computer-aided drug design arise from the difficulty of reliably predicting the binding affinity of a small molecule to a biolo...

(5-HT1A) receptor transiently expressed in COS-7 cells and of the native human 5-HT1A receptor derived from hippocampus and frontal cortex were identified by photoaffinity labeling with N-(p-azido-m-[125I]iodophenethyl)spiperone [( 125I]N3-NAPS), previously characterized as a high affinity ...
Identification of ligand-binding pockets in proteins is pivotal to protein function definition and drug discovery. In this study, we focus on determining the binding pockets in proteins for potential ligands without any a priori knowledge. Three methods based upon residue preference concept are proposed...
