Table 5.
Correlation between number of proteins that make up the enzymes of each amino acid biosynthetic pathway and their minimum amino acid bias.
| E. coli | S. typhimurium | B. subtilis | |
|---|---|---|---|
| Minimum bias | r (n = 20)a,b | r (n = 20)a,b | r (n = 20)a,b |
| Cognate | -0.49 (P < 0.003) | -0.72 (P < 0.004) | -0.23 (P < 0.21) |
| Non-cognate | -0.12 (P < 0.18) | -0.22 (P < 0.14) | -0.06 (P < 0.39) |
| Overall | -0.13 (P < 0.16) | -0.22 (P < 0.14) | -0.04 (P < 0.44) |
a
n represents the number of enzyme activities used to calculate the correlations. It can be determined from Table 2.
b
P represents the probability that the correlation is non-significant (see Experimental procedures).
