CueR activates transcription through a DNA distortion mechanism.

Chengli Fang, Steven J Philips, Xiaoxian Wu, Kui Chen, Jing Shi, Liqiang Shen, Juncao Xu, Yu Feng, Thomas V O'Halloran, Yu Zhang,

The MerR-family transcription factors (TFs) are a large group of bacterial proteins responding to cellular metal ions and multiple antibiotics by binding within central RNA polymerase-binding regions of a promoter. While most TFs alter transcription through protein-protein interactions, MerR TFs are capable of reshaping promoter DNA. To address the question ... Read more >>

Crystal structures and biochemical analyses of the bacterial arginine dihydrolase ArgZ suggests a "bond rotation" catalytic mechanism.

Ningning Zhuang, Hao Zhang, Lingting Li, Xiaoxian Wu, Chen Yang, Yu Zhang,

A recently discovered ornithine-ammonia cycle (OAC) serves as a conduit in the nitrogen storage and remobilization machinery in cyanobacteria. The OAC involves an arginine catabolic reaction catalyzed by the arginine dihydrolase ArgZ whose catalytic mechanism is unknown. Here we determined the crystal structures at 1.2-3.0 Å of unliganded ArgZ from ... Read more >>

Structural insights into the unique mechanism of transcription activation by Caulobacter crescentus GcrA.

Xiaoxian Wu, Diane L Haakonsen, Allen G Sanderlin, Yue J Liu, Liqiang Shen, Ningning Zhuang, Michael T Laub, Yu Zhang,

Canonical bacterial transcription activators bind to non-transcribed promoter elements to increase transcription of their target genes. Here we report crystal structures of binary complexes comprising domains of Caulobacter crescentus GcrA, a noncanonical bacterial transcription factor, that support a novel mechanism for transcription activation through the preferential binding of methylated cis-regulatory ...

Chronic Δ(9)-Tetrahydrocannabinol Administration Reduces IgE(+)B Cells but Unlikely Enhances Pathogenic SIVmac251 Infection in Male Rhesus Macaques of Chinese Origin.

Qiang Wei, Li Liu, Zhe Cong, Xiaoxian Wu, Hui Wang, Chuan Qin, Patricia Molina, Zhiwei Chen,

Delta9-tetrahydrocannabinol (Δ(9)-THC) is the major psychoactive component of the cannabis plant. Δ(9)-THC has been used in the active ingredient of Marinol as an appetite stimulant for AIDS patients. Its impact on progression of HIV-1 infection, however, remains debatable. Previous studies indicated that Δ(9)-THC administration enhanced HIV-1 infection in huPBL-SCID mice ... Read more >>

Therapeutic dendritic-cell vaccine for simian AIDS.

Wei Lu, Xiaoxian Wu, Yaozeng Lu, Weizhong Guo, Jean-Marie Andrieu,

An effective immune response against human immunodeficiency virus or simian immunodeficiency virus (SIV) is critical in achieving control of viral replication. Here, we show in SIV-infected rhesus monkeys that an effective and durable SIV-specific cellular and humoral immunity is elicited by a vaccination with chemically inactivated SIV-pulsed dendritic cells. After ... Read more >>
