Effect of Metallic Ions, Sucrose on the Activity of Aspartase and Analysis of the Active Part of the Enzyme;

Coli EP810 can produce transaminase with high activity and aspartase with low activity after culture.

Gene engineering techniques were used to generate aspartase mutant libraries and we got a mutant strain T 33 with 5 fold increase in aspartase activity Aspartase was purified from Mutant strain T 33 and its enzymatic characters were studied.

Preparation of L-4-fluorophenylalanine by aspartate aminotransferase method;

Study on extraction of aspartate aminotransferase by aqueous two phase system;

Aspartate aminotransferase to platelet ratio index as a non-invasive parameter for predicting liver fibrosis in chronic hepatitis B

Objective To examine the AST and ALP levels of the gingival crevicular fluidin patiens wearing Co-Cr based porcelain-fused-to-metal(PFM) crown and to study the effeccts of the crown on the periodontal tissue.

Cloning and prokaryotic expression of cathepsin D like aspartic protease gene of Clonorchis sinensis and analysis of immunogenicity of the recombinant protein;

The yapsins are a novel class of glycosylphosphatidyl inositol(GPI)-linked aspartic proteases in fungus.

Objective With the help of the bioinformatics to predict the deduced protein\'s structure and function,we identified cathepsin D-like aspartic protease from the full length cDNA plasmid library of Clonorchis sinensis in order to instruct the experiment.
