Table 1 Procedures used in Urzymology

From: The Rodin-Ohno hypothesis that two enzyme superfamilies descended from one ancestral gene: an unlikely scenario for the origins of translation that will not be dismissed

Process

Remarks

Superimpose homologs

POSA server: http://fatcat.burnham.org/POSA/

Clone & Express

Maltose Binding Protein (MBP) fusions; TEV cleavage

Characterize

Rate accelerations, substrate specificities

Authenticate
