Guo, Hong, Sun, Sheng, Finan, Turlough M., Xu, Jianping

Variation in genome size and content is common among bacterial strains. Identifying these naturally occurring differences can accelerate our understanding of bacterial attributes, such as ecological...

Substrate conformational transitions in the active site of chorismate mutase: Their role in the catalytic mechanism

Guo, Hong, Cui, Qiang, Lipscomb, William N., Karplus, Martin

Chorismate mutase acts at the first branch-point of aromatic amino acid biosynthesis and catalyzes the conversion of chorismate to prephenate. The results of molecular dynamics simulations of the...

Gapped DNA is anisotropically bent

Guo, Hong, Tullius, Thomas D.

Ionizing radiation damages DNA in several ways, including through formation of a single-nucleoside gap in one DNA strand. We have developed a two-dimensional gel electrophoresis method to investigate...

Locking the DNA topoisomerase I protein clamp inhibits DNA rotation and induces cell lethality

Woo, Michael H., Losasso, Carmen, Guo, Hong, Pattarello, Luca, Benedetti, Piero, Bjornsti, Mary-Ann

Eukaryotic DNA topoisomerase I (Top1) is a monomeric protein clamp that functions in DNA replication, transcription, and recombination. Opposable “lip” domains form a salt bridge to complete Top1...

Expression of Members of the 28-Kilodalton Major Outer Membrane Protein Family of Ehrlichia chaffeensis during Persistent Infection

Zhang, Jian-zhi, Guo, Hong, Winslow, Gary M., Yu, Xue-jie

The 28-kDa immunodominant outer membrane proteins (P28 OMPs) of Ehrlichia chaffeensis are encoded by a multigene family. As an indirect measure of the in vivo expression of the members of the p28...

Comparative Gene Genealogies Indicate that Two Clonal Lineages of Cryptococcus gattii in British Columbia Resemble Strains from Other Geographical Areas

Kidd, Sarah E., Guo, Hong, Bartlett, Karen H., Xu, Jianping, Kronstad, James W.

Cryptococcus gattii has recently emerged as a pathogen of humans and animals in the temperate climate of Vancouver Island, British Columbia (B.C.). The majority (∼95%) of the isolates from the...

Mechanism of histone methylation catalyzed by protein lysine methyltransferase SET7/9 and origin of product specificity

Guo, Hao-Bo, Guo, Hong

Methylation of certain lysine residues in the N-terminal tails of core histone proteins in nucleosome is of fundamental importance in the regulation of chromatin structure and gene expression. Such...

TOR Signaling Is a Determinant of Cell Survival in Response to DNA Damage▿ †

Shen, Changxian, Lancaster, Cynthia S., Shi, Bin, Guo, Hong, Thimmaiah, Padma, Bjornsti, Mary-Ann

The conserved TOR (target of rapamycin) kinase is part of a TORC1 complex that regulates cellular responses to environmental stress, such as amino acid starvation and hypoxia. Dysregulation of...

Alternative Mechanisms by Which Mediator Subunit MED1/TRAP220 Regulates Peroxisome Proliferator-Activated Receptor γ-Stimulated Adipogenesis and Target Gene Expression▿

Ge, Kai, Cho, Young-Wook, Guo, Hong, Hong, Teresa B., Guermah, Mohamed, Ito, Mitsuhiro, ...

Mediator is a general coactivator complex connecting transcription activators and RNA polymerase II. Recent work has shown that the nuclear receptor-interacting MED1/TRAP220 subunit of Mediator is...

Computer Virus Propagation in a Network Organization: The Interplay between Social and Technological Networks

Hsing Kenneth Cheng, Hong Guo

This paper proposes a holistic view of a network organization’s computing environment to examine computer virus propagation patterns. We empirically examine a large-scale organizational network...

Cyclin-dependent kinase phosphorylation of RUNX1/AML1 on 3 sites increases transactivation potency and stimulates cell proliferation

Zhang, Linsheng, Fried, Florence B., Guo, Hong, Friedman, Alan D.

RUNX1/AML1 regulates lineage-specific genes during hematopoiesis and stimulates G1 cell-cycle progression. Within RUNX1, S48, S303, and S424 fit the cyclin-dependent kinase (cdk) phosphorylation...
