Investigating Information Dynamics in Living Systems through the Structure and Function of Enzymes. [PDF]

open access: yesPLoS ONE, 2016
Enzymes are proteins that accelerate intracellular chemical reactions often by factors of 105-1012s-1. We propose the structure and function of enzymes represent the thermodynamic expression of heritable information encoded in DNA with post-translational
