evolution. For the article “Functional genomic analysis of the rates of protein evolution,” by Dennis P. Wall, Aaron E. Hirsh, Hunter B. Fraser, Jochen Kumm, Guri Giaever, Michael B. Eisen, and Marcus W. Feldman, which appeared in issue 15, April 12, 2005, of Proc. Natl. Acad. Sci. USA (102, 5483–5488; first published March 30, 2005; 10.1073/pnas.0501761102), the authors note that on page 5488, the 11th line of the first full paragraph appears incorrectly as follows:
If the effect of dispensability on the rate of protein evolution is entirely mediated by level of expression, as has been suggested (10, 15), then pDKN, in which case
It should read as follows:
If the effect of dispensability on the rate of protein evolution is entirely mediated by level of expression, as has been suggested (10, 15), then pDKN = 0, in which case
This error does not affect the conclusions of the article.
