ID 1.11.1.22 DE hydroperoxy fatty acid reductase. CA a hydroperoxy polyunsaturated fatty acid + H(+) + NADPH = a hydroxy CA polyunsaturated fatty acid + H2O + NADP(+). CC -!- The enzyme, characterized from the cyanobacterium Synechocystis CC PCC 6803, can reduce unsaturated fatty acid hydroperoxides and alkyl CC hydroperoxides. CC -!- The enzyme, which utilizes NADPH generated by the photosynthetic CC electron transfer system, protects the cells from lipid peroxidation. DR P74250, GPX1_SYNY3 ; P73824, GPX2_SYNY3 ; //
