Metabolic
design and biomimetic catalysis of archaic chemoauтotrophic
CO2 fixation cycle
Abstract
On the base of Bacteria and Archaea contemporary
metabolic pathways, which have an ancient phylogenetic roots, a new biomimetic
design of archaic autocatalytic chemoautotrophic cycle of CO2
fixation (CAF cycle) was proposed. The competition between archaic
chemoautotrophic cycles inside of CAF cycle should lead to chemical natural
selection of cycles in hydrothermal conditions of the ancient Earth. Physical
and chemical conditions of formation activated thioesters of CH3CO~SCH3
type (analogues acetyl-coenzyme A), activating of assimilation CO2 fixation cycles intermediates are
considered.
