Transport of 14C-labeled sugars by group A Streptococcus
| Strain | Apparent Km (μM)/Vmax (nmol/min/1010 CFU)a
|
||
|---|---|---|---|
| Glucose | Maltose | Maltotriose | |
| MGAS5005 | 4.5/135 | 12.5/67 | 2.1/127 |
| ΔmalE | 4.3/131 | 16.3/43 | 17.3/41 |
| compΔmalE | 5.1/142 | 11.5/72 | 1.9/139 |
Apparent Km values were determined by assuming that transport follows Michaelis-Menton kinetics.
