摘要:
There is provided a cell line that is prepared by transforming HEK293 cell with a human Kir2.1 gene using a retrovirus expression system, wherein the HEK293 expresses a stable α1G T-type calcium channel. The cell line responds sensitively to KCl and forms an appropriate level of the membrane voltage so that the cell signaling pathway may be investigated by the molecular biological and biochemical studies.
摘要:
A compound represented by a general formula (Ia) or (Ib) and a stereo-selective preparation method thereof using a carbonyl reductase which is separated from Kluyveromyces marxianus. The compound can be prepared by reduction of substituted β-keto ester and can be used as an intermediate in preparing β-lactam group antibiotics.
摘要:
Carbonyl reductase (CR) of a yeast strain, Kluyveromyces marxianus, and its isolation and purification method thereof is provided. The reduction reaction by the reductase obtained in the present invention is more stereospecific and requires less cost and time than the reduction reactions by the microorganisms or by the reducing enzymes obtained from a chemical synthesis.
摘要:
The invention is a gene coding for a quinone oxidoreductase from Kluyveromyces marxianus and a protein having an amino acid sequence expressed therefrom, which can be advantageously used in a reduction reaction of a quinone compound and synthesis of intermediates for a biologically active compound.
摘要:
The present invention relates to a gene coding for a thermostable DNA ligase from Aquifex pyrophilus, a hyperthermophilic Bacterium, a protein having an amino acid sequence expressed therefrom and a probe used for detecting said ligase DNA. More particularly, the present invention is directed to a gene having a base sequence of SEQ. ID. NO: 3 and a thermostable DNA ligase having an amino acid sequence expressed therefrom (SEQ. ID. NO: 4). Since Aquifex pyrophilus DNA ligase of the present invention has 75% of the ligation activity after heating at 95 ° C. for 1 hour, the ligase has higher stability than DNA ligases from the preexisting bacteria under high temperature and thus it can be advantageously used in genetic diseases assay of medical field, etc.

摘要:
Gene sequences of superoxide dismutase of Aquifex pyrophilus which is one of hyperthermophile microorganism and protein expressed therefrom are provided, wherein the protein is used as a necessary medicament in treatment of inflammation, disease of autoimmunization, chromosome lesion and the like, and particularly, A. pyrophilus is a hyperthermophile which can grow at the optimum temperature of 85.degree. C., and thus the superoxide dismutase of A. pyrophilus has a higher thermal stability than other organisms, resulting in further broad applications in the pharmaceutical field.
摘要:
Disclosed is a complex of the 11 kDa Ca2+ binding protein of 11 and Hepatitis B virus polymerase (HBVPol) which moves to Promyelocytic Leukemia Nuclear Body (PMLNB). Furthermore, the present invention discloses a method for controlling movement of the HBVPol/p11 complex into the nucleus of HepG2 cell with adjusting of intracellular Ca2+ ion concentration by administrating an agent for controlling calcium ion concentration in HepG2 cells.
