Characterization of an Agrobacterium tumefaciens D-psicose 3-epimerase that converts D-fructose to D-psicose.

• Hye-Jung Kim, Eun-Kyung Hyun, Yeong-Su Kim, Yong-Joo Lee, Deok-Kun Oh
• Applied and environmental microbiology
• 2006

The noncharacterized gene previously proposed as the D-tagatose 3-epimerase gene from Agrobacterium tumefaciens was cloned and expressed in Escherichia coli. The expressed enzyme was purified by… (More)

Ginsenoside compound K production from ginseng root extract by a thermostable beta-glycosidase from Sulfolobus solfataricus.

• Kyeong-Hwan Noh, Ju-Wan Son, Hye-Jung Kim, Deok-Kun Oh
• Bioscience, biotechnology, and biochemistry
• 2009

Ginsenoside compound K was produced from ginseng root extract using a thermostable recombinant beta-glycosidase from Sulfolobus solfataricus. The pH and temperature for maximum production were 5.5… (More)

Crystal structure of D-psicose 3-epimerase from Agrobacterium tumefaciens and its complex with true substrate D-fructose: a pivotal role of metal in catalysis, an active site for the…

• Journal of molecular biology
• 2006

D-psicose, a rare sugar produced by the enzymatic reaction of D-tagatose 3-epimerase (DTEase), has been used extensively for the bioproduction of various rare carbohydrates. Recently characterized… (More)

Combined operation of unified power-quality conditioner with distributed generation

• B. M. Han, Byung Chull Bae, Hye-Jung Kim, S. Baek
• IEEE Transactions on Power Delivery
• 2006

This paper describes analysis results of a combined operation of the unified power quality conditioner with the distributed generation. The proposed system consists of a series inverter, a shunt… (More)

Somatic Hypermutation in the Absence of DNA-Dependent Protein Kinase Catalytic Subunit (DNA-Pkcs) or Recombination-Activating Gene (Rag)1 Activity

• Mats Bemark, Julian E Sale, Hye-Jung Kim, Claudia Berek, Ruth A. Cosgrove, Michael Neuberger
• The Journal of experimental medicine
• 2000

Somatic hypermutation and isotype switch recombination occur in germinal center B cells, are linked to transcription, and are similarly affected by deficiency in MutS homologue (MSH)2. Class-switch… (More)

Purification and characterization of an L-arabinose isomerase from an isolated strain of Geobacillus thermodenitrificans producing D-tagatose.

• Hye-Jung Kim, Deok-Kun Oh
• Journal of biotechnology
• 2005

The araA gene, encoding l-arabinose isomerase (AI), from the thermophilic bacterium Geobacillus thermodenitrificans was cloned and expressed in Escherichia coli. Recombinant AI was isolated with a… (More)

Novel substrates of a ribose-5-phosphate isomerase from Clostridium thermocellum.

• Ran-Young Yoon, Soo-Jin Yeom, Hye-Jung Kim, Deok-Kun Oh
• Journal of biotechnology
• 2009

A substrate specificity study of the recombinant D-ribose-5-phosphate isomerase (RpiB) from Clostridium thermocellum was performed. Among all aldopentoses and aldohexoses, the RpiB enzyme displayed… (More)

Noninvasive molecular biomarkers for the detection of colorectal cancer.

• Hye-Jung Kim, Myeong-Hee Yu, H Y Kim, Jonghoe Byun, Cheolju Lee
• BMB reports
• 2008

Colorectal cancer (CRC) is the third most common malignancy in the world. Because CRC develops slowly from removable precancerous lesions, detection of the disease at an early stage during regular… (More)
