Abstract: A process for producing poly alpha-1,3-glucan with reduced molecular weight is disclosed. The process comprises contacting water, sucrose, a polar organic solvent, and a glucosyltransferase enzyme in a solution to produce poly alpha-1,3-glucan. This contacting step results in the production of poly alpha-1,3-glucan having a reduced molecular weight compared to the molecular weight of a poly alpha-1,3-glucan made in the absence of the polar organic solvent.

Abstract: The invention relates to a glucose dehydrogenase showing an NADP/NAD activity ratio, namely the value obtained by dividing the enzyme activity value obtained by using NADP as a coenzyme by the enzyme activity value obtained by using NAD as a coenzyme, of not lower than 300, to a gene coding therefor, and to a transformant harboring that gene. The enzyme of the invention is very high in NADP specificity and can be suitably used, for example, for NADPH production, for coenzyme regeneration in enzymatic reduction reactions, and in biosensors for glucose concentration measurements.

Abstract: Novel gene deletions and translocations involving chromosome 2 resulting in fusion proteins combining part of Anaplastic Lymphoma Kinase (ALK) kinase with part of a secondary protein have been identified herein in human solid tumors, e.g. non-small cell lung carcinoma (NSCLC). Secondary proteins include Echinoderm Microtubule-Associated Protein-Like 4 (EML-4) and TRK-Fusion Gene (TFG). The EML4-ALK fusion protein, which retains ALK tyrosine kinase activity, was confirmed to drive the proliferation and survival of NSCLC characterized by this mutation. The invention therefore provides, in part, isolated polynucleotides and vectors encoding the disclosed mutant ALK kinase polypeptides, probes for detecting it, isolated mutant polypeptides, recombinant polypeptides, and reagents for detecting the fusion and truncated polypeptides.
