Title : Cloning and sequence analysis of a cDNA for human
glycosylasparaginase
Abstract :
- A single gene encodes the subunits of this lysosomal amidase
- We have isolated a full-length cDNA (HPAsn.6) for human placenta glycosylasparaginase using a 221-bp PCR amplified fragment containing rat liver asparaginase gene sequences
- The deduced amino acid sequence from the human clone showed sequence identity to both the alpha and beta subunits of the rat enzyme
- The human enzyme is encoded as a 34.6 kDa polypeptide that is post-translationally processed to generate two subunits of approx
- 19.5 (alpha) and 15 (beta) kDa
- A charge enriched region is present at the predicted site where cleavage occurs
- Using polyclonal antibodies against the alpha and beta subunits of rat liver asparaginase , we have shown that the human enzyme is similar in structure to the rat enzyme
