Latest Patents

One of Cheng's latest patents is a DNA polymerase possessing continuous catalytic capacity and salt tolerance. This invention features a DNA polymerase with an amino acid sequence represented by SEQ ID NO:2, or a derivative of this sequence through substitution, deletion, or addition of at least one amino acid residue. The hybrid DNA polymerase is created by inserting a thioredoxin binding domain (TBD) from bacteriophage T7 DNA polymerase into a DNA polymerase I (Sau). The method for preparing this DNA polymerase involves several steps, including determining a target substitution sequence, synthesizing a primer, cloning the Sau-TBD segment into an expression vector, and inducing protein expression.

Another significant patent involves generating statistical views in a database system. This invention outlines techniques for executing a database workload by retrieving constraints, evaluating the workload to generate statistical view candidates, refining these candidates based on constraints, and ultimately generating statistical views from the refined candidates.
