摘要:
A webbing take-up device enabling a reduction in size of an overload release mechanism and easy adjustment of an operation torque of the overload release mechanism is provided. In the overload release mechanism of this webbing take-up device, rotary force of a large diameter gear is transmitted to a small diameter gear via plural annular friction springs. The friction springs are disposed between an inner periphery face of a main body portion of the large diameter gear and a tubular portion of the small diameter gear, side by side along an axial direction of the two gears. Consequently, a radial direction enlargement of the large diameter gear and small diameter gear due to space for disposing the friction springs may be restrained. Moreover, the operation torque of the overload release mechanism may be adjusted stepwise by changing the number of the friction springs to be used, in accordance with requirements.
摘要:
An object of the present invention is to provide an expression vector that allows for stable production of N-deacetylase/N-sulfotransferase 2 in large amounts and a process for production of N-deacetylase/N-sulfotransferase 2 using the same. The present invention provides a recombinant baculovirus expression vector obtained by incorporating into baculovirus DNA, a DNA fragment having lobster L21 DNA, DNA encoding gp67 signal peptide and DNA encoding the 79th to 883rd amino acids of human N-deacetylase/N-sulfotransferase 2 in this order in the 5′ to 3′ direction.
摘要:
The present invention provides O-glycan α2,8-sialyltransferase which has novel substrate specificity and substrate selectivity, and β-galactoside α2,6-sialyltransferase which has novel action and substrate specificity. The sialyltransferase of the present invention can be used as a medicament for suppression of cancer metastasis, prevention of virus infection, suppression of inflammatory response, or activation of neural cells.
摘要:
An oxidized phospholipid degrading enzyme is provided, which plays an important role in the oxygen stress preventive mechanism in organisms. The enzyme hydrolyzes a 1-acyl-2-.omega.-carboxyfatty acid acyl-3-phosphatidylcholine as a substrate at the 2-ester bond thereof to form 1-acyl-2-lyso-3-phosphatidylcholine. The activity of the enzyme is slightly enhanced by 4 mM calcium chloride. The molecular mass of the enzyme is 95.+-.5 kDa (by gel filtration). The enzyme is composed of three subunits whose molecular masses have been found to be 29 kDa, 30 kDa and 45 kDa, respectively, by SDS-polyacrylamide electrophoresis. A gene coding the enzyme is also provided. This gene is important for the synthesis of the enzyme by genetic engineering.
