Replacement of either residue forming the covalent linkages to the cofactor (Cys166 or His104) with Ala resulted in a decrease in the midpoint potential of the flavin and in lower rates of substrate turnover.
We found an increase of G/C nucleotides and a decrease in A/T nucleotides at the midpoint, as described recently for human cell lines (Valouev et al., 2011).
Therefore, they must be due to qualitative complex I modifications such as those leading to a decrease in the reduction state and/or the reducing midpoint potential of the complex I ROS generator/s.
Tail current analysis (Figure 1C) in the presence PBA resulted in a left-shift of the midpoint of activation (V1/2) and a decrease in the voltage-dependence (z) of Q1/E1 complexes (Table 1).
"Ivan took a decrease in compensation last year.
"There is a decrease in fidelity".
It is a grouped scatterplot that shows approximately parallel ascending regression lines within each level of Z, but a decreasing sequence of midpoints.
Some prokaryotes use redox pairs that have only a small difference in midpoint potential.
But decreases were measured too, including a 19percentt decrease in reports of criminal mischief and an 11percentt decrease in menacing.
