Glyoxysomal malate dehydrogenase ec 1.1.1.37 of watermelon cotyledons de novo synthesis on cytoplasmic ribosomes


, : Glyoxysomal malate dehydrogenase ec 1.1.1.37 of watermelon cotyledons de novo synthesis on cytoplasmic ribosomes. Planta (Heidelberg) 134(3): 277-285

The development of glyoxysomal malate dehydrogenase (gMDH, EC 1.1.1.37) during early germination of watermelon seedlings (Citrullus vulgaris Schrad.) was determined in the cotyledons by radial immunodiffusion. The active isoenzyme was absent in dry seeds. By density labeling with deuterium oxide and incorporation of [14C] amino acids it was shown that the marked increase of gMDH activity in the cotyledons during the first 4 days of germination was due to de novo synthesis of the isoenzyme. The effects of protein synthesis inhibitors (cycloheximide and chloramphenicol) on the synthesis of gMDH indicated that the glyoxysomal isoenzyme was synthesized on cytoplasmic ribosomes. Possible mechanisms by which the glyoxysomal malate dehydrogenase isoenzyme reaches its final location in the cell are discussed.
