It has been found that changing arginine-179 of the a subunit to leucine does not inactivate the enzyme, but does cause marked a

In order to gain further Insight into this interesting problem, we undertook the protein structural analysis of the crystalline OATase from pig kidney.

Mechanistic Analysis of the Aspartate Aminotransferase Active Site Mutants—Y70F, K258A, and R292Dphic analysis showed that the dicarboxylic amino acid substrate specificity is dictated by ion pairing with R292. The mutation R292D converts the title enzyme to a cationic amino acid transaminase, which preferentially catalyzes the transamination of Arg or Lys over Asp or Glu.
