Ecological Aspects of the Distribution of Different Autotrophic CO 2 Fixation Pathways

Abstract: Autotrophic CO 2 fixation represents the most important biosynthetic process in biology. Besides the wellknown Calvin-Benson cycle, five other totally different autotrophic mechanisms are known today. This minireview discusses the factors determining their distribution. As will be made clear, the observed diversity reflects the variety of the organisms and the ecological niches existing in nature.Autotrophic CO 2 fixation represents the most important biosynthetic process in nature, being responsible for the n… Show more

“…Besides the requirement for a high energy yield at high stress, a further problem for thermophiles is the thermal instability of certain chemicals. For example, photosynthesis occurs only below 73 1C, in part because of the thermal instability of intermediates of the Calvin-Benson-Bassham Cycle (Berg, 2011). The lack of Cyanobacteria at high temperatures within the current study is consistent with this effect.…”

“…A number of phyla were only observed in samples from below 80 1C, including Cyanobacteria, Acidobacteria, Verrucomicrobia and Planctomycetes. The absence of Cyanobacteria at high temperature is consistent with the established upper temperature limit for photosynthesis (73 1C) (Berg, 2011). Crenarchaeota, Deinococcus-Thermus and Aquificae were observed in the highest abundance at 460 1C.…”

“…Some examples of attractive natural carboxylases are employed in alternative natural carbon fixation pathways, thus far five alternative autotrophic CO 2 fixation pathways have been discovered (Berg, 2011). Moreover, attractive carboxylases can be embedded in synthetic CO 2 fixation pathways, which have been extensively explored by computational analyses (e.g.…”

“…Four types of structural RubisCOs are currently distinguished, of which two types, form I (CbbLS) and form II (CbbM), are known to operate in the classical autotrophic CB cycle (Tabita et al, 2007). RubisCO is present in all plants, cyanobacteria and many autotrophic bacteria (Berg, 2011) and is believed to be the most abundant protein on Earth (Ellis, 1979;Raven, 2009). Hence, the CB cycle and the RubisCO enzymes are of fundamental importance for global primary production and it is vital to better understand RubisCO evolution and its diversity.…”
