摘要:
The invention relates to ceramidase having the following structural motif Z1-X1-H-X2-T-L-X2-X2-X2-X2-Q-X2-X2-D-E-Z2, wherein the X1 position represents an aromatic amino acid (F, Y or W), all X2 positions represent any independent amino acids, and Z?1 and Z2¿ are any polypeptides.
摘要:
The present invention relates to an isolated target sequence. The target sequence is a splice variant of PDE5 called a PDE5a1, a component of which is presented as SEQ ID No 1. The identified target sequence of the present invention may be used to as a target to identify agents (such as modulators) useful in the prevention and/or treatment of a disease associated with scarring and/or fibrosis or to selectively identify smooth muscle cells and myofibroblasts and myoepithelial cells in samples of normal and diseased tissue from individuals.
摘要:
A method for quantitating a specific component in lipoproteins contained in a biological sample, for example, HDL (high-density lipoprotein), LDL (low-density lipoprotein) or VLDL (very low-density lipoprotein) by using a commonly employed automatic analyzer without centrifuging or making the reaction liquor cloudy due to complexes or aggregates. Namely, a controlling means, whereby an enzyme reaction can be carried out exclusively for the target component, is introduced into a method for enzymatically assaying a component in a specific lipoprotein fraction in the serum, thereby specifically assaying the component.
摘要:
A process is disclosed for transcribing ribonucleic acids of a sample by treating the ribonucleic acid-containing sample with a DNA-decomposing enzyme in the presence of MN2+ ions, then by transcribing the ribonucleic acids into deoxyribonucleic acids. Also disclosed are appropriate reagents for carrying out this process.
摘要:
A method is provided for identifying a methylated CpG containing nucleic acid including contacting a nucleic acid with a methylation sensitive restriction endonuclease that cleaves unmethylated CpG sites, contacting the sample with an isoschizomer of the methylation sensitive restriction endonuclease, wherein the isoschizomer cleaves both methylated and unmethylated CpG sites. The method also includes adding an oligonucleotide under conditions and for a time to allow ligation of the oligonucleotide to nucleic acid cleaved by the restriction endonuclease, and amplifying the nucleic acid. A method is also provided for detecting an age associated disorder including contacting a nucleic acid with a methylation sensitive restriction endonuclease that cleaves unmethylated CpG sites, contacting the sample with an isoschizomer of the methylation sensitive restriction endonuclease, wherein the isoschizomer cleaves both methylated and unmethylated CpG sites. The method also includes adding an oligonucleotide under conditions and for a time to allow ligation of the oligonucleotide to nucleic acid cleaved by the restriction endonuclease, and amplifying the nucleic acid. The amplified digested nucleic acid is adhered to a membrane, and hybridized with a probe of interest. A kit useful for detection of a CpG containing nucleic acid is also provided.

Novel multi-binding compounds are disclosed that modulate enzymatic processes. The compounds of the invention comprise from 2-10 ligands covalently connected, each of said ligands being capable of binding to an enzyme, enzyme substrate or enzyme cofactor thereby modulating the biological processes/functions thereof.
摘要:
A method of detecting an enzyme-mediated DNA cleavage reaction in a fluorometric assay is provided. The method can be used to detect DNA cleavage caused by restriction endonucleases, retroviral integrase enzymes, DNases, RNases, or enzymes utilized in other strand separating processes in molecular biology.
摘要:
The present invention concerns methods and systems for predicting the biological function(s) of proteins. The invention is based on the development of functional site descriptors for discrete protein biological functions. Functional site descriptors are geometric representations of protein functional sites in three-dimensional space, and can also include additional parameters, for example, conformational information. Following their development, one or more functional site descriptors (for one or more different biological funtions) are used to probe protein structures to determine if such structures contain the functional sites described by the corresponding functional site descriptors. If so, the protein(s) containing the functional site(s) are predicted to have the corresponding biological function(s). In preferred embodiments, a library of functional site descriptors is used to probe inexact protein structures derived by computational methods from amino acid sequence information to predict the biological function(s) of such sequences and of the gene(s) encoding the same.
