Examination of the Ligand-Binding and Enzymatic Properties of a Bilin-Binding Protein from the Poisonous Caterpillar Lonomia obliqua
The bilin-binding proteins (BBP) from lepidopteran insects are members of the lipocalin family of proteins and play a special role in pigmentation through the binding of biliverdin IXγ. Lopap, a BBP-like protein from the venom of the toxic caterpillar Lonomia obliqua has been reported to act as a serine protease that activates the coagulation proenzyme prothrombin. Here we show that BBPLo, a va...
متن کاملStructure-Based Protein-Ligand Binding
This lecture first talked about the uncertainty and dynamics in the protein-ligand docking, and then reviewed some methods for flexible protein-ligand docking. In this subsection, we will talk about the possible uncertainties in crystal structures from X-ray diffraction. Interpretation of X-ray raw data. The raw diffraction data are generally converted to an electron density map by inverting th...
متن کاملLigand configurational entropy and protein binding.
The restriction of a small molecule's motion on binding to a protein causes a loss of configurational entropy, and thus a penalty in binding affinity. Some energy models used in computer-aided ligand design neglect this entropic penalty, whereas others account for it based on an expected drop in the number of accessible rotamers upon binding. However, the validity of the physical assumptions un...
متن کاملLigand binding and protein dynamics in neuroglobin.
Neuroglobin (Ngb) is a recently discovered protein in vertebrate brain tissue that belongs to the globin family of proteins. It has been implicated in the neuronal response to hypoxia or ischemia, although its physiological role has been hitherto unknown. Ngb is hexacoordinate in the ferrous deoxy form under physiological conditions. To bind exogenous ligands like O(2) and CO, the His E7 endoge...
متن کاملمطالعه شیمی فیزیکی ساختمان لیزوزیم به روش ligand binding
پروتئینها فراوان تری مولکولهای آلی در بدن جانداران می باشند. آنزیم ها یکی از مهمترین نوع پروتئینهای کروی می باشند که بعضی از فعالیتهای حیات بدانها وابسته است . لیزوزیم اولین آنزیم شناخته شده است . این آنزیم دارای 129 واحد اسید آمینه در زنجیر پلی پپتیدی و چهار پیوند سیستئین درون زنجیری می باشد. لیزوزیم به دلیل دارا بودن اسید آمینه های باردار توان پذیرش بعضی از لیگاندها را دارا می باشد. در این پا...
