The Leloir pathway: a mechanistic imperative for three enzymes to change the stereochemical configuration of a single carbon in galactose

TL;DR: The structure of the enzyme reveals many details of the binding of NAD+ and inhibitors at the active site, and appears to have been guided by the principle of economy in the evolution of binding sites.

Molecular genetics of nucleotide sugar interconversion pathways in plants.

TL;DR: The genetic characterization of nucleotide sugar interconversion enzymes has the potential to understand the regulation of these complex metabolic pathways and to permit the modification of cell wall material by changing the availability of monosaccharide precursors.

On the Nature of Allosteric Transitions: A Plausible Model

TL;DR: "It is certain that all bodies whatsoever, though they have no sense, yet they have perception, and whether the body be alterant or alterec, evermore a perception precedeth operation; for else all bodies would be like one to another."

A Method for Determining the Sedimentation Behavior of Enzymes: Application to Protein Mixtures

TL;DR: Sucrose gradient centrifugation is found to be a suitable method for determining sedimentation coefficients of enzymes in protein mixtures and the sedimentation behavior of several of the enzymes in the pathway of histidine biosynthesis in S. typhimurium has been determined.
