Both enzymes were expressed in E. coli cells, with (LlA) or without (EcAIII) a His-tag sequence. The proteins were purified, yielding 6 or 30 mg.L(-1) of culture, respectively. The enzymes are heat-stable up to 60 degrees C and show both isoaspartyl dipeptidase and l-asparaginase activities. Kinetic parameters for both enzymatic reactions have been determined, showing that the isoaspartyl peptidase activity is the dominating one. Despite sequence similarity to aspartylglucosaminidases, no aspartylglucosaminidase activity could be detected. Phylogenetic analysis demonstrated the relationship of these proteins to other asparaginases and aspartylglucosaminidases and suggested their classification as N-terminal nucleophile hydrolases. This is consistent with the observed autocatalytic breakdown of the immature proteins into two subunits, with liberation of an N-terminal threonine as a potential catalytic residue."xsd:string |
