摘要:
The present invention pertains to the use of the protein phenylalanine ammonia-lyase, as well as the biologically-active derivatives of the said protein for preventing or treating diseases associated with a phenylalanine imbalance in a human or animal body. More particularly, the present invention relates to the therapeutic use of the above-cited molecules for preventing or treating a phenylalanine imbalance in vivo. This invention also deals with therapeutic compositions comprising a pharmaceutically active amount of the above-described therapeutic molecules as well as with therapeutic methods using the said therapeutic compositions. Finally, the present invention relates to processes for selecting more therapeutically-effective variants of said protein as well as to the selected variants themselves.

摘要:
The present invention is directed to phenylalanine ammonia-lyase (PAL) produced by prokaryotes, wherein such prokaryotic PAL wherein the PAL variant has a greater phenylalanine-converting activity and/or a reduced immunogenicity as compared to a wild-type PAL. The invention thus provides compositions of bacterial PAL and biologically active fragments, mutants, variants and analogs thereof, as well as methods for the production, purification, and use of such compositions for therapeutic and industrial purposes.
摘要:
The present invention provides a recombinant human α-L-iduronidase and biologically active fragments and muteins thereof with a purity greater than 99%. The present invention further provides large-scale methods to produce and purify commercial grade recombinant human α-L-iduronidase enzyme thereof.
摘要:
A method and apparatus for gaging the cross-sectional bore diameter generated by an abrading type finishing tool in an abrading machine. The tool and plug gage are mechanically mounted to the same spindle with the plug sized to a predetermined diameter and mounted behind the machining element. The plug gage is indexed to enter the bore being machined at predetermined cycles to determine if an undersize condition of the tool exists. Failure of the plug gage to enter the bore would indicate an undersize condition of the tool and upon the gage entering the bore it would indicate a correct tool size. The invention has further apparatus for shutting down the machine in the event an undersize condition is determined.
摘要:
An apparatus and method are provided for roll sizing the periphery of cylindrical workpieces to finish and size the workpiece to a close tolerance diameter. The method and apparatus can also be used to prefinish and presize cylindrical workpieces in preparation for subsequent forming of spline teeth or gear teeth and the like on the workpiece periphery.
摘要:
The present invention provides polynucleotide sequences (bbp) encoding a Bak Binding Protein (BBP) and fragments thereof that bind to Bak. The invention also provides a BBP which binds to Bak. The invention also provides recombinant host cells containing polynucleotides encoding BBP. The invention further provides antibodies that specifically bind to BBP. The invention further provides methods for detecting agents such as drugs that alter the binding of a BBP with a Bak protein. The invention further provides methods for detecting the presence of bbp or BBP in a biological sample, and further provides methods for modulating the levels of BBP in a cell. This invention additionally encompasses novel peptides, designated the “BBP Binding Domains” and the respective nucleotides, designated “bbpbd-1” and “bbpbd-2” which are involved in the interaction between Bak and BBP.
摘要:
The present invention provides a highly purified recombinant, human precursor N-acetylgalactosamine-4-sulfatase and biologically active mutants, fragments and analogs thereof as well as pharmaceutical formulations comprising highly purified recombinant human precursor N-acetylgalactosamine-4-sulfatase. The invention also provides methods for treating diseases caused all or in part by deficiencies in human N-acetylgalactosamine-4-sulfatase including MPS VI and methods for producing and purifying the recombinant precursor enzyme to a highly purified form.

Thin wall, torque sensitive pinion gears, sun gears or other such workparts are driven in rotation in a fixture during honing of the internal diameter to minimize out-of-roundness. The fixture for honing multiple workparts at a time includes a workpart driving means having multiple workpart driving gears each meshed with a respective one of the workparts. Each workpart driving gear is mounted on a hollow rotatable bushing arranged end-to-end with respect to adjacent bushings and dog-bone shaped driver members interconnect and are drivingly received in adjacent bushings. Means is connected to one of the dog-bone shaped members to rotate same and thereby cause the workpart driver gears to rotate the workparts in unison during honing.
