DESCRIPTION (provided by applicant): This application requests partial support for a meeting on Iron Sulfur Enzymes as part of a the Gordon Research Conference series to be held in Mount Holyoke College (South Hadley, MA) on June 10-15, 2012 with a broad and long-term goal of bringing together the world's leading experts in iron-sulfur clusters, focusing on enzymatic mechanisms, biogenesis, roles in regulation and in human disease in a uniquely cross-disciplinary manner. First organized in 1994 to focus on nitrogenase and its unique iron sulfur chemistry, knowledge about iron sulfur clusters has grown exponentially in the last two decades and, in 2006, the name of the conference was changed accordingly to Gordon Conference on Iron Sulfur Enzymes. The conference has tremendous breadth, featuring sessions on numerous iron sulfur enzymes of unicellular organisms, animals and plants, which provide important insights into how these versatile proteins are synthesized and utilized. Proteins containing iron-sulfur cofactors perform a variety of biological functions, ranging across electron transfer, acid- base catalysis, and sensing where they are agents for cell regulation through transcription (DNA) or translation (RNA). They are redox catalysts for radical-based reactions and the activation of H2, N2 and CO2, processes that offer scientific and economic challenges for industry. Iron-sulfur centers provide the focus for fundamental investigations of chemical bonding, spectroscopy, structure and molecular mechanism, and their functions have numerous implications for health, medicine and applications for technology, including renewable energy. The specific aim of this conference is to include distinguished speakers and discussion leaders from many fields, and topics will range from mechanistic discussions of bacterial enzymes to discussions of an emerging class of human diseases characterized by abnormalities in their iron-sulfur cluster biogenesis pathway. The health relatedness of the meeting is clear and will be discussed extensively. Three new diseases that result from mutations of genes in the iron-sulfur biogenesis pathway have been discovered since 2010, and there are no effective therapies for any of the diseases, including Friedreich ataxia, a disease characterized by progressive neurodegeneration and progressive heart failure. Novel therapeutic strategies are needed, and mixing the chemists and medical doctors together for the first time has the potential to catalyze progress in the field. PUBLIC HEALTH RELEVANCE: Iron sulfur cofactors are essential for virtually all forms of life, and much progress has been made on understanding their special chemical attributes and their unique contributions to metabolism. In the last ten years, it has become clear that failure to correctly synthesize iron sulfur clusters and proteins causes a range of rare and serious diseases, ranging from infantile lactic acidosis and seizures to Friedreich ataxia, a disease in which patients survive until early adulthood, and ISCU myopathy, in which patients have a normal lifespan, but have marked impairment of skeletal muscle function. The discussion of current research at this Gordon Research Conference will define important questions and problems that are associated with a growing list of unique diseases, and this is a crucial opportunity to bring researchers together to work on development of mechanistic insight into how iron-sulfur clusters are assembled and transferred, which may lead to new treatment strategies for diseases of iron sulfur cluster deficiency.

描述（申请人提供）：此申请要求对在霍利奥克山学院举行的戈登研究会议系列的一部分，铁硫酶会议的部分支持（南哈德利，马萨诸塞州）于2012年6月10日至15日举行，其广泛而长期的目标是汇集世界领先的铁硫簇专家，专注于酶机制，生物发生，以独特的跨学科方式在监管和人类疾病中发挥作用。首次组织于1994年，专注于固氮酶及其独特的铁硫化学，有关铁硫簇的知识在过去二十年中呈指数级增长，2006年，会议名称相应地更改为戈登铁硫酶会议。会议具有巨大的广度，包括单细胞生物，动物和植物的众多铁硫酶的会议，这些会议为这些多功能蛋白质的合成和利用提供了重要的见解。含有铁-硫辅因子的蛋白质执行各种生物学功能， 电子转移、酸碱催化和传感，其中它们是通过转录（DNA）或翻译（RNA）进行细胞调节的试剂。它们是用于自由基反应和H2、N2和CO2活化的氧化还原催化剂，这些过程为工业带来了科学和经济挑战。铁硫中心为化学键、光谱学、结构和分子机制的基础研究提供了焦点，它们的功能对健康、医学和技术应用（包括可再生能源）具有许多影响。本次会议的具体目标是包括来自许多领域的杰出演讲者和讨论领导者，主题将从细菌酶的机制讨论到讨论一类以铁硫簇生物合成途径异常为特征的新兴人类疾病。会议的健康相关性是明确的，将进行广泛讨论。自2010年以来，已经发现了三种由铁-硫生物合成途径中的基因突变引起的新疾病，并且对任何疾病都没有有效的治疗方法，包括弗里德赖希共济失调，一种以进行性神经变性和进行性心力衰竭为特征的疾病。需要新的治疗策略，首次将化学家和医生混合在一起有可能促进该领域的进展。 公共卫生关系：铁硫辅因子是几乎所有形式的生命所必需的，并且在了解其特殊的化学属性及其对代谢的独特贡献方面取得了很大进展。在过去的十年里，人们已经清楚，未能正确合成铁硫簇和蛋白质会导致一系列罕见和严重的疾病，从婴儿乳酸性酸中毒和癫痫发作到弗里德赖希共济失调（患者生存到成年早期的疾病）和ISCU肌病，其中患者的寿命正常，但骨骼肌功能明显受损。在这次戈登研究会议上对当前研究的讨论将定义与越来越多的独特疾病相关的重要问题和问题，这是一个至关重要的机会，可以让研究人员聚集在一起，共同研究铁硫簇如何组装和转移的机制，这可能会导致铁硫簇缺乏症疾病的新治疗策略。
