摘要:
A method for efficiently searching compounds capable of inhibiting steroid sulfatase activity and thus being useful in treating hormone-dependent diseases such as mammary cancer which comprises treating cells having a steroid sulfatase gene transferred thereinto with the compounds to be tested and then judging the proliferation of the cells.
摘要:
A phytase having a low Km value against phytic acid; a process for the preparation of the phytase by using a microorganism having the ability to generate and accumulate the phytase; and feed containing the phytase. The novel phytase can hydrolyze phytic acid (acting as antinutritional factor) contained in feed, which brings about an enhancement in the nutritive value of the feed, and permits the efficient utilization of phosporic acid liberated by the hydrolysis.
摘要:
A novel DNA encoding a selection marker and a novel DNA serving as a promoter/terminator which are appropriate for a transformation system of a fungus belonging to the genus Monascus and the expression of a recombinant DNA; and a novel transformation system of a fungus belonging to the genus Monascus wherein the monascus is transformed by a vector containing the above-described DNA encoding a selection marker and the promoter/terminator sequence together with a DNA encoding a desired protein, culturing the resultant transformant and thus obtaining the expression product of the recombinant DNA at a high level.
摘要:
A fused polypeptide composed of a polypeptide having the G-CSF activity with another polypeptide having the TPO activity; a DNA encoding this fused polypeptide; a fused polypeptide wherein a polypeptide having the G-CSF activity has been fused with another polypeptide having the TPO activity via a spacer peptide; a DNA encoding this fused polypeptide; a polypeptide wherein the above-mentioned fused polypeptide composed of the polypeptide having the G-CSF activity with the polypeptide having the TPO activity has been further chemically modified with a polyalkylene glycol derivative; and a remedy for anemia containing such a fused polypeptide as the active ingredient.
摘要:
The invention relates to a method for controlling the activity of an immunologically functional molecule, such as an antibody, a protein, a peptide or the like, an agent of promoting the activity of an immunologically functional molecule, and an immunologically functional molecule having the promoted activity.
摘要:
A phytase that has a low Km value with respect to phytic acid and is inexpensive; a DNA encoding the phytase; a recombinant DNA comprising the above DNA integrated thereinto; a transformant having the recombinant DNA; a process for producing the phytase by using the transformant; and a feed prepared by using the phytase.
摘要:
Peptides having cyclic structures represented by the following general formula (I): R (X ) (X ) (X ) (X ) (X ) (X ) (X ) (X ) (X ) (X ) (X ) (X ) (X ) (X ) (X ) (X ) (X ) R and exerting the effect of restoring a P53 protein activity on P53 protein mutants or pharmacologically acceptable salts thereof. In said formula (I) X means an arbitrary member selected from among X to X while n means an arbitrary member selected from among n to n (provided that i is an integer of from 1 to 17), then X represents an amino acid residue or an organic acid residue; a functional group in a residue X selected among X to X (provided that p is an integer of from 1 to 11) and a functional group X selected from among X to X (provided that q is an integer of from 8 to 17 and larger than p) form a cyclic structure having a crosslinkage selected from among S-S, S-CH2-S, S-CH2-C6H4-CH2-S, S-CH2-CO, CO-NH, NH-CO, O-CO or CO-O; R represents optionally substituted alkanoyl, etc.; and R represents optionally substitued alkoxy, etc.
