Proteins in boldface are those that have never been observed experimentally previous to this study.

P value, probability that the null hypothesis is true, based on a two-tailed Student t test of ratio1 versus ratio 2.

Normalized to the value obtained for CipA.

Standard error was calculated using the simple quotient rule of error propagation, where a protein's ratio on Avicel, its ratio on cellobiose, CipA's ratio on Avicel, and CipA's ratio on cellobiose were considered random and independent.
