FUNCTIONAL AND STRUCTURAL ASPECTS OF POPLAR CYTOSOLIC AND PLASTIDIAL TYPE A METHIONINE SULFOXIDE REDUCTASES
Overview
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. Cys(46) is the, catalytic cysteine, and the two C-terminal cysteines, Cys(196) and, Cys(202), are implicated in the thioredoxin-dependent recycling mechanism., Inspection of the pMsrA x-ray three-dimensional structure, which has been, ...
