Transcription analyses of sialometabolism genes in Rd and derived mutant strains.
| Gene expression ratio: | |||
|---|---|---|---|
| strain | siaP | nanE | siaR |
| Rd | 2.1 | 3.2 | 2.2 |
| siaR | 1.0 | 0.9 | - |
| nanE | 0.7 | - | 1.3 |
| siaP | - | 0.9 | 0.9 |
| siaQ/M | 0.8 | 1.7 | 1.1 |
| crp | 1.4 | 2.2 | 1.3 |
| Rd (CDM) | 4.8 | 3.8 | 2.1 |
Values given are for the ratio of the expression level of the gene following growth in BHI in the absence of added Neu5Ac to growth with added Neu5Ac, taken from the data given in Figure 6. Also shown are the values for strain Rd following growth on CDM medium. A dashed line indicates no expression following inactivation of the respective gene.
