MetNetAligner: a web service tool for metabolic network alignments (2009)

Cheng, Qiong, Harrison, Robert, Zelikovsky, Alexander

Summary: The accumulation of high-throughput genomic, proteomic and metabolical data allows for increasingly accurate modeling and reconstruction of metabolic networks. Alignment of the reconstructed...

iC2mpi: A Platform for Parallel Execution of Graph-Structured Iterative Computations (2008)

Harnish Botadra, Qiong Cheng, Sushil K. Prasad

Parallelization of sequential programs is often daunting because of the substantial development cost involved. Various solutions have been proposed to address this concern, including directive-based...

Mapping and Filling Metabolic Pathways (2008)

Qiong Cheng, Dipendra Kaur, Robert Harrison, Er Zelikovsky

Abstract. Network mappings are extensively used for comparing, exploring, and predicting biological networks, are essential for pathway database search and also helpful for finding and filling...

Zelikovsky: Homomorphisms of Multisource Trees into Networks with Applications to Metabolic Pathways (2008)

Qiong Cheng, Robert Harrison, Er Zelikovsky

Network mapping is a convenient tool for comparing and exploring biological networks; it can be used for predicting unknown pathways, fast and meaningful searching of databases, and potentially...

Optimal mapping of multi source trees into dag in biological network (2007)

Qiong Cheng, Er Zelikovsky

Abstract. The effective and efficient prediction and reconstruction of biological networks for a variety of inter-species and intra-species organisms have been a challenging research topic in...

Cloning and Characterization of a Gene Cluster for Cyclododecanone Oxidation in Rhodococcus ruber SC1

Kostichka, Kristy, Thomas, Stuart M., Gibson, Katharine J., Nagarajan, Vasantha, Cheng, Qiong

Biological oxidation of cyclic ketones normally results in formation of the corresponding dicarboxylic acids, which are further metabolized in the cell. Rhodococcus ruber strain SC1 was isolated from...

Genetic Analysis of a Gene Cluster for Cyclohexanol Oxidation in Acinetobacter sp. Strain SE19 by In Vitro Transposition

Cheng, Qiong, Thomas, Stuart M., Kostichka, Kristy, Valentine, James R., Nagarajan, Vasantha

Biological oxidation of cyclic alcohols normally results in formation of the corresponding dicarboxylic acids, which are further metabolized and enter the central carbon metabolism in the cell. We...

Novel Carotenoid Oxidase Involved in Biosynthesis of 4,4′-Diapolycopene Dialdehyde

Tao, Luan, Schenzle, Andreas, Odom, J. Martin, Cheng, Qiong

Biosynthesis of C30 carotenoids is relatively restricted in nature but has been described in Staphylococcus and in methylotrophic bacteria. We report here identification of a novel gene (crtNb)...

Diversity of Carotenoid Synthesis Gene Clusters from Environmental Enterobacteriaceae Strains

Sedkova, Natalia, Tao, Luan, Rouvière, Pierre E., Cheng, Qiong

Eight Enterobacteriaceae strains that produce zeaxanthin and derivatives of this compound were isolated from a variety of environmental samples. Phylogenetic analysis showed that these strains...
