24. Diversity of C1-fixation pathways Growth on C1-compounds: carbondioxide, carbonmonoxide, methane, methanol, methylamines, formate and formaldehyde. Diversity of carboxylation reactions. Making C-C-bonds: defining chemically reactive positions in C1-accepting molecules: Ribulose-1,5-bisphosphate, Acetyl-CoA and Propionyl-CoA as CO2 acceptors, Ribose 5-monophosphate and Glycine as acceptors of Formaldehyde, the Carbonmonoxide-Dehydrogenase reaction. CO2-fixation pathways in phototrophs and chemotrophs: Calvin cyle (RuBP pathway), acetyl-CoA-pathway, reductive TCA, serin pathway, RuMP pathway. Evolutionary implication of the distribution of C1-fixing key enzymes.
