Postharvest Variation in Cell Wall-Degrading Enzymes of Papaya (Carica papaya L.) during Fruit Ripening.

abstract：:A high affinity cAMP-binding protein (cABP II) was purified to homogeneity from wheat germ. The apparent molecular weight of cABP II, as determined from gel exclusion chromatography, is 5.2 x 10(5) (at low ionic strength) and 2.8 x 10(5) (at high ionic strength). One polypeptide subunit (molecular weight, 80,000) was ...
