The highly liquid investments had maturities of 3 months or less when they were purchased. The stock investments will be sold in the next 6 to 12 months.
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. Provisional Patent Application Nos. The invention further relates to the use of such optimal compositions of PAL for therapeutic and industrial purposes.
This invention also relates to histidine ammonia-lyase HAL analogs, compositions containing such analogs, and related compositions. A representative list of PALs includes: Histidine ammonia-lyase HAL, E. Acta, 2pp. A representative list of HALs includes: Phenylketonuria PKU is an inborn error of amino acid metabolism that results from impaired activity of hepatic phenylalanine hydroxylase PAHthe enzyme responsible for the metabolism of phenylalanine.
For patients that have severe PKU, there is the potential for irreversible mental retardation unless phenylalanine is controlled at low levels using dietary restrictions.
PAL converts phenylalanine to ammonia and trans-cinnamic acid, a harmless metabolite, which is further metabolized and excreted in the urine as hippurate Hoskins, et al.
Current treatment for PKU involves the adherence to a restricted diet for life that is low in proteins and the amino acid phenylalanine Levy, Proc.
This dietary therapy is difficult to maintain Matalon, et al. Most low phenylalanine diet products have organoleptic properties sufficiently unsatisfactory that compliance with this treatment is compromised Levy, H.
Therefore, development of a therapeutic treatment would assist the current dietary treatment and prevent the neurological damages inflicted on those individuals with PKU, particularly for those patients with the most severe forms of the disease.
InScriver and colleagues reported their initial studies on the use of the enzyme PAL from Rhodosporidium toruloides Sarkissian, C.
However, the sensitivity of PAL to protease inactivation low activity in gastric conditions due to protease degradation and the reduced half-life found after repeated in vivo injection due to elicitation of an immune response limits further development of the native PAL protein as a clinical therapeutic.
Other Therapeutic Uses The use of PAL for cancer treatment has also been suggested based on its ability to limit the nutrient supply of phenylalanine to cancer cells and thereby inhibit neoplastic growth Fritz, et al. However, intravenously injected pegylated PAL was cleared rapidly from circulating blood after the 13th injection.
In addition, PAL-mediated reduction in phenylalanine prevented the proliferation of murine leukemia and metastatic melanoma Abell, et al.
PAL has also been used for tyrosinemia Marconi, W. Histidine ammonia-lyase HAL has been used in enzyme substitution therapy for histidinemia treatment. Histidinemia is an autosomal recessive disorder of histidine metabolism due to defective HAL, and is traditionally a benign condition Taylor, R.
PAL also has agricultural importance, being the initial enzymatic process leading to the phenylpropaniods that produce lignins, coumarins, and flavaniods in plants, fungi, and bacteria.
Hence, modulation of PAL activity can influence a number of agricultural phenomena such as the browning of fruit. In addition, structure-based drug design of active site PAL inhibitors could lead to effective herbicides Poppe, L. Although PAL potentially has various industrial and therapeutic applications, the use of PAL may be limited by reduced specific activity and proteolytic instability.
Similar to other therapeutic proteins, use of PAL as an enzyme therapy is accompanied by several disadvantages such as immunogenicity and proteolytic sensitivity.
Further, a delicate balance is required between substrate affinity and enzyme activity to achieve and maintain control of plasma phenylalanine levels within a normal somewhat narrow range in disorders characterized by hyperphenylalanemia.
As yet, a concerted effort toward improving these parameters has not been made due to a paucity of structural and biochemical knowledge regarding this protein. Protein Therapeutics and Effective Redesign for Therapeutic Advantage Numerous proteins are used therapeutically to alleviate metabolic deficiencies caused by genetic disorders.
Williams and Wilkins Companyinterferon-alpha for hepatitis C or cancer treatment, and adenosine deaminase for severe combined immunodeficiency SCID therapy Russell, et al.
Unfortunately, the lifetimes of these injected foreign proteins are usually diminished due to acute allergic reactions and rapid clearance from the bloodstream.

The efficacy of protein therapeutics can be improved with protein engineering methods, including rational design, directed evolution, chemical modification, and combinatorial optimization strategies. Rational design requires the availability of three-dimensional structural information and consideration of side-chain orientations and mobilities in the context of the structure, combined with generic properties such as side-chain hydrophobicity, polarity, charge, electronic contributions, and propensities to form specific secondary structures.
Among rational protein modification methods, a most promising solution involves producing variants using structure-based protein engineering.Problem A Joey Cuono started his own consulting firm, Cuono Company, on June 1, The trial balance at June 30 is shown below.
