| Comments |
"The free fraction
is 12%, which corresponds to
~700 RNAPs or a concentration of
free RNAPs of ~1µM, much higher
than an old estimate (30 nM) that has
been widely used in models of gene
regulation (15), but similar to a more
recent estimate (0.5-1.1µM, depending
on growth conditions (primary source))." |
