For kinetic constants,
the table is color-coded by relative log values of
1/KM, kcat, and kcat/KM compared to WT.
log 1/KM is used so that larger values are "better".

For T50 and TM values and Rosetta scores, a linear scale is used.

Blue shading indicates a variant that is "worse" than WT.
Orange shading indicates a variant that is "better" than WT.

Variants shaded black expressed (as confirmed by gel electrophoresis and/or yield > 0.1 mg/mL).
Variants marked with an asterisk (*) expressed, but no yield was recorded.

How were these data calculated?
