Gordon Research Conference Molecular Basis of Microbial One-Carbon Metabolism
The 12th one-carbon meeting will cover a variety of topics, including: (a) genomics, metagenomics, and proteomic studies of microbial communities in diverse environments that are increasing our understanding of autotrophy and C-1 metabolism and the evolution of these pathways; (b) redox regulation of carbon cycles and the interrelationship between the carbon cycle and other biogeochemical cycles (sulfur, nitrogen, oxygen); © novel pathways for carbon assimilation; (d) biotechnology related to C-1 metabolism; (e) novel enzyme mechanisms including channeling of C-1 intermediates during metabolism; (f) the involvement of C-1 compounds in the origins of metabolism and life; and (f) the relationship between metal homeostasis and the global carbon cycle.
