The values reported are the means ± SD of a minimum of four determinations. *, P < 0.05, compared with corresponding parental strain by using a two-sample t test. ND, not detected.
Cyb2p activity was measured as l-lactate-dependent cytochrome c reductase activity. The values reported are nanomoles of cytochrome c per minute per milligram of protein.
