From a twenty-first century 'omic' perspective, it is difficult not to reinterpret this substructure as genes linked to their expression products through a network of physical interactions, with cellular phenotypes, both structural and functional, emerging from this network.
The next step in his research, Keller says, will be using ever-better microscopy techniques to further explore how functional development emerges from cellular activities, especially within the nervous system.
In a recent analysis performed with dissipative metabolic networks (DMNs) we have shown that this global functional structure emerges in metabolic networks with a relatively high number of catalytic elements, under particular conditions of enzymatic covalent regulatory activity.
Understanding the organization of modules and their structural and functional roles emerges as a new challenge when studying biological networks.
Contrary to expectation, these ICNs were strikingly similar in all species, suggesting that functional laterality emerges early in the primate lineage (Fig. 3).
The concept of topological scale is, however, important for studying how functional interaction emerges from the structure of the physical PIN (Fig. 1A).
Given such a set of candidate genes, the prioritization of these genes for functional validation emerges as a key challenge in biomedical informatics [ 1].
We illustrate how a functional domain emerges as combination of prototypes by the example of Glycosyltransferase superfamily (orange oval in Fig. 4). Figure 5 shows glycogen synthase (PDB 1rzu), which catalyzes the elongation of alpha-1,4-glucose backbone.
In wild-type, PpcAM58N and PpcAM58K, the order of oxidation of the haem groups is maintained, but in the mutants a different functional mechanism emerges in which a 2e− step coupled with proton transfer is observed.
It seems superfluous to have two lineages with peptide binding abilities, but with the complete conservation of the predicted peptide binding groove in typical Z lineage sequences, a specific conserved and important functional role emerges for this lineage.
