Abstract excerpt
This report is about only deleting one C-terminal residue of D-hydantoinase to result in obvious changes on its molecular form and stability. A recombinant D-hydantoinase (P479) and its mutant enzyme deleted at C-terminal residue Arg (P478) were prepared by methods of gene cloning, expression and purification. Results show that the subunit molecular weight of P479 and P478 is the same (54kDa) as determined by...
