A cDNA coding for glutathione S-transferase (GST) was cloned and seque
nced from the unicellular green algae Coccomyxa sp. The predicted 215
amino acid polypeptide (23.9 kDa, pI 5.3) is most similar to the theta
-type GSTs found in a variety of different eukaryotic organisms. Withi
n this sub-class, the Coccomyxa GST is 42% identical (63% similar) to
the flatfish Pleuronectes platessa homologue, and 24 to 35% (49-57%) t
o other theta-type GST's.
