中文摘要
这个子项目是许多研究子项目中的一个
由NIH/NCRR资助的中心赠款提供的资源。子项目和
研究者(PI)可能从另一个NIH来源获得了主要资金,
因此可以在其他CRISP条目中表示。所列机构为
研究中心,而研究中心不一定是研究者所在的机构。
我们研究病毒的结构及其组成部分。我们感兴趣的是
组装途径以及病毒如何识别、进入和感染宿主。我们广泛使用电子显微镜来研究不能结晶的病毒或病毒片段。相对低分辨率的图谱可以通过蛋白质组分的晶体学研究来增强。
1.黄病毒:
西尼罗河病毒的结构(Mukhopadhyay等2003,Science 302)。小晶体是可利用的,其目前的分辨率约为20 A。
黄病毒组分的结构,如E蛋白(Zhang et al. 2004,Structure 12)和衣壳蛋白单独或与潜在药物复合;病毒酶。例如聚合酶、与E.
2.甲病毒:
有包膜的罗斯河病毒和辛德毕斯病毒的结构(Zhang等2002,J.Virol 76)。晶体可用于辛德比斯和小晶体的衍射质量未知的罗斯河。
甲病毒组分的结构,如E1和E2蛋白、单独的衣壳蛋白或与药物复合的衣壳蛋白。
3.细小病毒科:
几种细小病毒的衣壳结构(Simpson等2002,JMB 315;Kaufmann等2004,PNAS 101)。晶体可用于IHHNV,虾病原体。
正在尝试结晶PPV和B19衣壳蛋白的PLA 2独特区域。晶体可用于中和抗体的Fab片段。
4.小核糖核酸病毒:
配体如脊髓灰质炎病毒受体、CD 4和ICAM-1的结构(Zhang et al 2004,J Virol 78; Xiao et al 2005,Structure 13)。
5.瘟病毒:
甲基转移酶,聚合酶(Choi et al 2002,PNAS 101)
6. T4噬菌体的结构组分:
到目前为止,我们已经解决了约40种蛋白质中的约12种(例如,Fokine等人,2005,PNAS 102)。
7.其他建筑物的结构组成:
phiX 174(Bernal等,2004,JMB 337),phiKZ(Fokine等,2005,JMB 352),phi 29(Morais等,2005,Mol.Cell 18)。

英文摘要
This subproject is one of many research subprojects utilizing the
resources provided by a Center grant funded by NIH/NCRR. The subproject and
investigator (PI) may have received primary funding from another NIH source,
and thus could be represented in other CRISP entries. The institution listed is
for the Center, which is not necessarily the institution for the investigator.
We study the structure of viruses and their components. We are interested in the
assembly pathways and how viruses recognize, enter and infect their host. We make extensive use of electron microscopy to study viruses, or fragments of viruses, that cannot be crystallized. The relatively low resolution maps can be augmented by crystallographic studies of the protein components.
1. Flaviviruses:
Structure of West Nile virus (Mukhopadhyay et al 2003, Science 302). Small crystals are available that diffract currently to about 20A resolution.
Structure of components of flaviviruses such as E protein (Zhang et al. 2004, Structure 12) and capsid protein alone or in complex with potential drugs; viral enzymes. e.g. polymerase, Fab structures in complex with E.
2. Alphaviruses:
Structures of the enveloped Ross River Virus and Sindbis virus (Zhang et al 2002, J.Virol 76). Crystals are available for Sindbis and small crystals of unknown diffraction quality for Ross River.
Structure of components of alphaviruses such as E1 and E2 protein, capsid protein alone or in complex with drugs.
3. Parvoviridae:
Capsid structures of several parvoviruses (Simpson et al 2002, JMB 315;Kaufmann et al. 2004, PNAS 101). Crystals are available for IHHNV, a shrimp pathogen.
Attempts are being made to crystallize the PLA2 unique region of the capsid protein of PPV and B19. Crystals are available for Fab fragments of neutralizing antibodies.
4. Picornaviruses:
Structure of ligands such as polio virus receptor, DAF and ICAM-1 (Zhang et al 2004, J Virol 78; Xiao et al 2005, Structure 13).
5. Pestiviruses:
methyl transferase, polymerase (Choi et al 2002, PNAS 101)
6. Structural components of T4 phage:
We have solved about 12 out of about 40 proteins so far (e.g. Fokine et al. 2005, PNAS 102).
7. Structural components of other phages:
phiX174 (Bernal et al. 2004, JMB 337), phiKZ (Fokine et al. 2005, JMB 352), phi29 (Morais et al. 2005, Mol.Cell 18).
