... transporters to determine whether they are of endo- symbiotic origin from the captured cyanobacterium, of host origin, or of a 'mixed' origin from both of these sources. Our analysis has afforded ... thus clearly a case in which the endosymbiont benefits from host metabo- lism. The ancient origin of these transporters in the tree of photosynthetic...

... are likely to have orig- inated independently of proteins [56-59], the binding of ligands with primordial proteins would also be a critical step in the origin of life. Thus, it is intriguing to ... the origin of primitive proteins benefited from ligand binding, which is reasonable in terms of the thermodynamics of ligand binding and protein folding.
