| Comments |
"[Primary source] reported two different
Ks values (depending on the concentration
of the amino acids in the medium) corresponding
to two systems for amino acid uptake: a specific
permease for each aromatic amino acid with
high affinity (10^-7 M) and a nonspecific permease
with low affinity (10^-5 M)." Ks is the "half-velocity constant"—the value of S when µ/µmax = 0.5, S is the concentration of the limiting substrate for growth |
