Abstract: The present disclosure is directed to the properties of certain glycosyltransferase variants having N-terminal truncation deletions or internal deletions. Any of the mutants disclosed in here exhibit alpha-2,6-sialyltransferase enzymatic activity in the presence of CMP-activated sialic acid as co-substrate, and in the presence of a suitable acceptor site. A fundamental finding documented in the present disclosure is that these enzymes are not only capable of catalyzing transfer of a sialidyl moiety but they are also capable of catalyzing hydrolytic cleavage of terminally bound sialic acid from a glycan.

Abstract: This invention provides an amadoriase that acts on the ?-chain of hemoglobin A1c (HbA1c) and generates hydrogen peroxide, a method for measurement of HbA1c using such amadoriase, and a reagent kit for measurement of HbA1c using such amadoriase. The method for measurement of HbA1c involves the use of an amadoriase that has specific activity of 0.1 U/mg or greater to ?F6P and oxidizes the HbA1c ?-chain amino terminus so as to generate hydrogen peroxide, and the reagent kit for measurement of HbA1c comprises such amadoriase. The method and the kit for measurement of HbA1c enable quantification of HbA1c to be performed rapidly, simply, and accurately.

Abstract: Disclosed is a conjugate of a protein having substantial L-asparagine amino hydrolase activity and polyethylene glycol. In particular, the polyethylene glycol has a molecular weight of about 5000 Da and the protein is an L-asparaginase from Erwinia. The conjugate of the invention has shown superior properties such as maintenance of a high level of in vitro activity and an unexpected increase in half-life in vivo. Also disclosed are methods of producing the conjugate and use of the conjugate in therapy. In particular, a method is disclosed for use of the conjugate in the treatment of cancer, particularly Acute Lymphoblastic Leukemia (ALL). More specifically, a method is disclosed for use of the conjugate as a second line therapy for patients who have developed hypersensitivity or have had a disease relapse after treatment with other L-asparaginase preparations.
Abstract: A therapeutic agent for the treatment of toxemia, preeclampsia and eclampsia and a method for preparing the therapeutic agent are disclosed. The therapeutic agent is a stable pharmaceutical preparation containing, but not limited to, digestive/pancreatic enzymes. The therapeutic agent may be manufactured by a variety of encapsulation technologies. Delivery of the therapeutic agent may be made orally, through injection, by adherence of a medicated patch or by other methods. Further, a method of using the presence of chymotrypsin in the maternal GI tract as a biomarker, to determine the likelihood of developing preeclampsia, a pregnancy induced hypertension, and eclampsia/toxemia is disclosed.
Abstract: The invention relates to materials and methods of conjugating a water soluble polymer to an oxidized carbohydrate moiety of a blood coagulation protein comprising contacting the oxidized carbohydrate moiety with an activated water soluble polymer under conditions that allow conjugation. More specifically, the present invention relates to the aforementioned materials and methods wherein the water soluble polymer contains an active aminooxy group and wherein an oxime linkage is formed between the oxidized carbohydrate moiety and the active aminooxy group on the water soluble polymer. In one embodiment of the invention the conjugation is carried out in the presence of the nucleophilic catalyst aniline. In addition the generated oxime linkage can be stabilized by reduction with NaCNBH3 to form an alkoxyamine linkage.

Abstract: The present invention is a method for the biosynthesis of hundreds of compounds, mainly found in the cannabis plant. The starting material for these compounds can be any biological compound that is used/produced in a biological organism from the sugar family starting materials or other low cost raw materials processed via enzymes or within organisms to give final products. These final products include, but are not limited to: cannabinoids, terpenoids, stilbenoids, flavonoids, phenolic amides, lignanamides, spermidine alkaloids, and phenylpropanoids. Specifically, the present invention relates to the regular, modified, or synthetic gene(s) of select enzymes that are processed and inserted into an expression system (for example, a vector, cosmid, BAC, YAC, phage) to produce modified hosts. The modified host is then optimized for efficient production and yield via manipulation, silencing, and amplifying inserted or other genes in the host, leading to an efficient system for product.
