Resource allocation in metabolic networks: kinetic optimization and approximations by FBA.

abstract：:Beta galactosidases (BGALs) are glycosyl hydrolases that remove terminal β-D-galactosyl residues from β-D-galactosides. There are 17 predicted BGAL genes in the genomes of both Arabidopsis (BGAL1-17) and tomato (TBG1-17). All tested BGALs have BGAL activity but their distinct expression profiles and ancient phylogenet...
