TABLE 3.
Ratio of incorporation of [14C]purine bases into AMP to that of incorporation into GMP of RNAa
| Purine added | AMP/GMP incorporation ratio
|
|
|---|---|---|
| H. volcanii | H. halobium | |
| Adenine | 1.23 ± 0.05 | 0.92 ± 0.05 |
| Guanine | 0.24 ± 0.01 | <0.01 |
| Hypoxanthine | 0.67 ± 0.05 | 0.64 ± 0.06 |
Cells were grown in liquid medium. Incorporation was determined as described in Materials and Methods. Values are means of three experiments ± standard deviations.
