Fig. 7. Expression of recombinant P. duboscqi salivary adenosine deaminase
(ADA). cDNAs encoding P. duboscqi salivary ADA (PduM73 and PduM74)
were cloned into PCRT7NT-TOPO vector, and recombinant proteins were expressed
in E. coli. The affinity column-purified proteins (lane 1, PduM73;
lane2, PduM74; lane 3, empty plasmid vector) were analyzed by SDS-PAGE and
then subjected to (A) western blotting and (B) Coomassie blue staining.
