The hierarchical organization of autocatalytic reaction networks and its relevance to the origin of life
Fig 4
A minimal autocatalytic motif within biochemical tier-1 SDASs.
This autocatalytic motif is one of the motifs detected by applying the integer programming procedure to SDAS-bio-1a, with the criterion that the motif should contain as few reaction types as possible. This motif is centered around phosphorylated monosaccharides and small carboxylic acids.
