Strain | NADP-GDH Activity (μmol/min/mg)a | NAD-GDH Activity (μmol/min/mg)b | ||
---|---|---|---|---|
YNDex | YNAceRaf | YNDex | YNAceRaf | |
Wild Type | 154+26 | 24+6c | 6.2+4.3 | 108+13c |
gdh1Δ | 1.0+0.4 | 3.2+1.1d | 5.8+6.3 | 14+2d, e |

NADP-dependent measures Gdh1p and Gdh3p activity. Data are the average +/− standard error for 4 or 5 separate determinations.
NAD-dependent measures Gdh2p activity. Data are the average +/− standard error for 2 or 3 (YNDex) or 5 (YNAceRaf) separate determinations.
p < 0.001 by t-test as compared to activity of the same strain in glucose.
p < 0.08 by t-test as compared to activity of the same strain in glucose.
p< 0.001 by t-test as compared to activity of wild type or gdh3Δ in YNAceRaf.
