cDNAs of the two-domain arginine kinase and its separated domains 1 and 2 from Anthopleura japonicus, are cloned into the plasmid pMAL, and recombinant enzymes are expressed in Escherichia coli as MBP fusion proteins | Anthopleura japonica |
Protein Variants | Comment | Organism |
---|---|---|
D62E | introduction of Glu at position 62 in isolated domain 2. The catalytic efficiency of D2/D62E is similar to that of the two-domain wild-type enzyme. This replacement does not alter synergistic substrate binding relative to wild-type domain 2 | Anthopleura japonica |
D62G | introduction of Gly at position 62 in isolated domain 2. The catalytic efficiency of the D2/D62G mutant is decreased to 13% that of wild-type domain 2 | Anthopleura japonica |
