Triparanol Inhibition of Sterol Biosynthesis in Chlorella ellipsoidea.

abstract：:Hydrogen peroxide (H(2)O(2)) induces increases, to different degrees, in transcripts, protein levels, and activity of the Ndh complex (EC 1.6.5.3). In the present work, we have compared the effects of relatively excess light, H(2)O(2), dimethylthiourea (a scavenger of H(2)O(2)), and/or EGTA (a Ca(2+) chelator) on the ...
