Ecosystem consequences of species richness and composition in pond food webs.

abstract：:Enzymes are the subset of proteins that catalyse the chemistry of life, transforming both macromolecular substrates and small molecules. The precise three-dimensional architecture of enzymes permits almost unerring selectivity in physical and chemical steps to impose remarkable rate accelerations and specificity in pr...
