| The genome of Populus trichocarpa contains five methionine sulfoxide reductase A genes. Here, both cytosolic (cMsrA) and plastidial (pMsrA) poplar MsrAs were analyzed. The two recombinant enzymes are active in the reduction of methionine sulfoxide with either dithiothreitol or poplar thioredoxin as a reductant. In both enzymes, five cysteines, at positions 46, 81, 100, 196, and 202, are conserved. Biochemical and enzymatic analyses of the cysteine-mutated MsrAs support a catalytic mechanism involving three cysteines at positions 46, 196, and 202. Cys46 is the catalytic cysteine, and the two C-terminal cysteines, Cys196 and Cys202, are implicated in the thioredoxin-dependent recycling mechanism. Inspection of the pMsrA x-ray three-dimensional structure,... |

| Dans ce papier, nous nous intéressons au problème de réduction (ou simplification) des expressions booléennes. Nous présentons une approche différente des approches connues, telles que celles de Karnaugh et Quine-Mc Clusky. L'expression est modélisée sous la forme de chemins d'expression comprenant des termes ascendants et descendants. La simplification consiste à trouver les ascendants irréductibles.
