While the structure of the chloroplast ribosome is very similar to that of a eubacterial ribosome, structures of the mitochondrial ribosomes (or mitoribosomes) are found to be highly divergent. The two mitoribosomes that we have studied include a protistan (Leishmania tarentolae) and a mammalian (Bos taurus) species, both with significantly smaller sizes of ribosomal RNAs (rRNAs), compared to those in a eubacterial ribosome. In fact, the L. tarentolae mitochondrial rRNAs are among the smallest rRNAs known. Effect of reduction in size of rRNA on the function of the mammalian mitoribosome will be presented.   \n\u003C\/p\u003E\n\u003Cp\u003EFor more information contact \u003Ca href=\u0022mailto:loren.williams@chemistry.gatech.edu\u0022\u003EProf. Loren Williams\u003C\/a\u003E (404-894-9752) or \u003Ca href=\u0022mailto:steve.harvey@biology.gatech.edu\u0022\u003EProf. Steve Harvey\u003C\/a\u003E (404-385-4498).\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"Dr. Raj Agrawal, New York State Department of Health\n\nStructural organization of organellar ribosomes, as revealed by cryo-EM\n\nBiochemistry Divisional Seminar Series","format":"limited_html"}],"field_summary_sentence":[{"value":"Prof. Raj Agrawal"}],"uid":"27275","created_gmt":"2009-10-08 00:00:00","changed_gmt":"2016-10-08 01:47:13","author":"Shirley Tomes","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2009-10-21T16:00:00-04:00","event_time_end":"2009-10-21T17:00:00-04:00","event_time_end_last":"2009-10-21T17:00:00-04:00","gmt_time_start":"2009-10-21 20:00:00","gmt_time_end":"2009-10-21 21:00:00","gmt_time_end_last":"2009-10-21 21:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"85951","name":"School of Chemistry and Biochemistry"}],"categories":[],"keywords":[{"id":"919","name":"Biochemistry"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cstrong\u003EShirley Tomes\u003C\/strong\u003E\u003Cbr \/\u003EChemistry \u0026amp; Biochemistry\u003Cbr \/\u003E\u003Ca href=\u0022http:\/\/www.gatech.edu\/contact\/index.html?id=st81\u0022\u003EContact Shirley Tomes\u003C\/a\u003E\u003Cbr \/\u003E\u003Cstrong\u003E404-894-0591\u003C\/strong\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
