Isolation and characterization of a cDNA encoding glutathione transferase from ripe Eksotika 2 papaya

P. F. Lam and U. K. Abu Bakar

Abstract

A cDNA clone encoding glutathione transferase, PGST1, was isolated from a ripe Eksotika 2 papaya cDNA library. The cDNA is 968 bp. The 218 deduced amino acid sequence has a calculated molecular weight of 25.4 kD and an isoelectric point of 5.9. It has amino acid sequence similarities to other glutathione transferases. The gene is highly expressed in ripe fruit.
